Still, the details of what’s about to happen to a transitioning industry are unclear. CNBC spoke with more than a dozen leaders who have been among the most influential decision-makers and thinkers in the TV industry over the past two decades to get a sense of what they think will happen in the next three years.

CNBC asked the same set of questions to each interviewee. The following is a sampling of their answers.

In three years, will legacy TV effectively die?

Peter Chernin, The Chernin Group chairman and CEO: It will continue to be in decline. It will be crappier. Budgets will get cut. More scripted programming will migrate away to streaming. There will be more repeats. But it will continue to exist. One of the really interesting questions here – this will be fascinating – the core of linear TV is sports rights. The NFL deal starts next season and is double the price of the previous one. That will suck even more money out of programming budgets. Then you’ve got the NBA deal, those renewal talks will happen this year. That will probably double in price. So you’ve got increasing prices of the most high-profile sports and declining number of homes watching. That will eat away at everything else.

Kevin Mayer, Candle Media co-CEO: It only has a few years left. It’s nearing the end. For entertainment that has no need to be viewed at any specific time, that’s already done. It’s already largely shifted to streaming. Next will be the end of scripted programming on broadcast networks. There’s zero need for that. That’s going to come to a close in the next two or three years. When ESPN finally pulls the plug, the bundle is effectively over. And that will happen relatively soon. Linear TV is in its final death throes.

Barry Diller, IAC chairman: It’s dying, but while syndication is around, even if its diminished, it will still be here. The tail end of these things lasts much longer than anyone predicts.

Ann Sarnoff, former Warner Bros. chairwoman and CEO: The linear bundle will definitely be around in three years, but the number of subscribers will continue to decline, and the average age of the viewers will continue to increase steadily. One big X factor regarding how the cable channel universe evolves will be sports and how big a role streaming services play in sports. The fragmentation of sports rights is good for the leagues but confusing for consumers. The most passionate sports fans will subscribe to everything and find their sport wherever it is, but fragmentation creates a delicate tightrope for the leagues to walk in terms of maintaining mass appeal and engagement, which have driven a stellar sports advertising business.

Bill Simmons, The Ringer founder: Three years feels way too short to me. I think it’s going to play out like it has with terrestrial radio and digital audio. Five years ago, you could have said radio would absolutely be dead soon, and nobody would have challenged you. But it’s still limping along even with much heavier competition from podcasts, streaming, TikTok and everyone else. Even with ad markets dwindling and the advertising being much more localized, it’s not close to being dead yet. It’s like when Michael Corleone says how Hyman Roth has been dying of the same heart attack for the last 20 years. That’s radio. And linear TV will be the same way. It will have a Hyman Roth death, not a Sonny Corleone death.

Jeff Zucker, former CNN president: It will continue to exist. Obviously it will have fewer subs than it does today. News and sports will keep it alive.

Richard Plepler, former HBO CEO: While linear is obviously not the wave of the future, cash flow is cash flow, which means it still hangs on to some form of life.

Bela Bajaria, Netflix chief content officer: Since I started in this business in 1996, people have always talked about linear TV dying. Definitely the pie will be smaller in three years. But there are so many people who watch linear TV, especially sports and news. It will be smaller, but not gone.

Kathleen Finch, Warner Bros. Discovery U.S. networks chief content officer: Linear TV will absolutely still be here. When you look at the size and scope of the linear TV business, it’s huge. People still like to sit down as a group in front of the TV. It’s very communal. And advertisers love it — whether they’re selling a new movie coming out or launching a car sale. The linear TV business will be healthy for a long time. Obviously people’s habits are changing, but as a business, it’s a large, robust, high-margin business. One of the other things so important about linear is it provides the financial ecosystem to feed a lot of streaming platforms. In our group at WBD, it makes about 4,000 hours a year of content, and it’s a huge amount of content that we make to feed the networks. A lot get a second life on streaming – or a first life based on what we determine. To fund the content just for streaming is a bit of a challenge. But because we really have a great margin with a dual revenue system, we super serve that audience on linear.

Byron Allen, Entertainment Studios founder and CEO: I think linear TV will exist for a very, very long time. I believe that all of these various platforms – they’re not instead of, they’re additive. Look at human behavior and how we consume content, we’ve only made a richer landscape. When there was the industrial revolution, it was fueled by oil and gas. This is the digital revolution, and it’s fueled by content. Local TV will still be here and much needed. You need local news. And let’s not forget the networks — ABC, CBS, Fox, NBC, the big four broadcasters — have locked up the true religion of America, the NFL, for the next 11 years. So you will be watching those networks for sports. Not just on streaming. I think that contract tells you the bundle is here for a while.

Wonya Lucas, Hallmark Media president and CEO: I don’t think this is the death of linear. I just don’t. I think that linear will still be alive and thriving. I do think there will be some shakeout in terms of which services survive and which ones don’t and which ones are bundled together, and there will be some consolidation. I don’t think everyone can have independence. But I think when we start bundling the cost of all the streaming services, you’re looking at the same cost of a cable package at some point.

Chris Winfrey, Charter Communications CEO: It won’t be effectively dead, but it will be significantly more expensive and have fewer subscribers. A lot of that has to do with the rising cost of sports rights. The new NFL rights extension deal will generate about twice as much cost per year starting in the 2023-24 season. That cost is now being distributed over an increasingly smaller base of subscribers, which is pushing up the overall cost of content. But in the next three years, there will still be customers who can afford it. It’ll just be much, much smaller and more expensive. Eventually there will have to be a restructuring of the business.

In three years, which major streaming services will definitely exist?

Ex-CNN boss Zucker: Netflix, Amazon Prime Video, Apple and the Disney suite [Hulu, ESPN+ and Disney+]. The fifth could be a combo of the remainders: HBO Max, Paramount+ and Peacock.

Jeff Bewkes, former Time Warner CEO: Netflix, Amazon, Disney, HBO Max. Maybe one more that doesn’t make much money or is about break even and hovers near death.

Chernin Group’s Chernin: All of them with the caveat that there may be some combination of Paramount, Peacock and HBO Max. The big guys don’t want to buy any of them with exception with HBO.

IAC’s Diller: There’s only one streaming service that’s dominant, now and forever, and that’s Netflix. But many others will exist.

Jeff Hirsch, Starz President and CEO:  Disney, Netfilix, Warner Bros. Discovery, Amazon … and of course, Starz.

Candle Media’s Mayer: Apple TV+, Disney+, Netflix, Amazon Prime, Max, probably. Paramount+ will be folded in, Peacock will folded in. Maybe they’ll be combined with a smaller service like Starz.

The Ringer’s Simmons: You have Hulu, Peacock and Paramount out there as candidates to get swallowed up by a bigger streamer, but who’s doing it? Apple never does anything. Amazon doesn’t need to do anything. HBO/Discovery just went through two mergers in six years. Netflix never does anything. Disney/ESPN seems more likely to shed stuff than buy stuff. So unless Comcast goes on a crazy spending spree, I don’t see anything changing — I think everyone will still be around, just with less employees and way less original content.

Netflix’s Bajaria: Netflix, of course. Disney+ has such a strong library. Many of the others will be interesting. You’re already seeing Showtime and Paramount+ come together. Does Hulu stay in Disney, or does Comcast buy their share out? Does Warner Bros. Discovery stay with Discovery+ and HBO Max, or does it merge with another company? There will be a lot of movement and changes in the streaming landscape. 

Will there be a cable-like bundle of several major streaming services?

Candle Media’s Mayer: Yes, I think so. I don’t know if we’ll see bundles between entertainment companies, but there will be some version of a bigger bundle of content you’ll be able to buy at your choice.

Aryeh Bourkoff, LionTree chairman and CEO: It’s more about self-bundling content and other offerings to generate platform and brand loyalty from the consumer. What I think you will also see is the eventual release of exclusive premium content to multiple platforms to better monetize the best content, but the most successful platform relationships will be self-bundled.

Ex-Time Warner boss Bewkes: I doubt it. I don’t see why you’d need it. Any aggregator’s role would be taking any of the leading streamers and attaching what are laggard, subscale channels. I’m not sure it’s compelling.

IAC’s Diller: I do think there will probably be a more efficient way of buying more streaming services, but I don’t think it will be analogous to the cable bundle. One central warehouse who deals with all players and sends one bill — that I don’t think is going to happen. I think it will be somewhat chopped up. But there may be multiplicity, where there may be a much easier way to access a group of streamers than dealing with them individually.

Naveen Chopra, Paramount Global CFO: I think it’s very possible but not necessarily inevitable. On one hand, bundles have tremendous value in terms of increasing acquisition costs, lowering churn and the convenience for consumers. It’s something we definitely embrace. We’ve done a lot of bundles and partnerships that we’ve been very successful with, whether that’s with Sky in Europe or Walmart or T-Mobile in the U.S. A broader bundle that incorporates multiple streaming services could offer some of the same benefits. But there are two really big things you have to solve in trying to effectuate that kind of bundle. The economics is one dimension, and the other is the user interface and customer relationship. Today, streaming services have independent user interfaces and streamers like to own the relationship with the customer. So, you have to give up some economics to be part of that bundle and still have a way of sharing information and enough control over the UI to help build and maintain audiences around the content. There is some experimentation going on with all of these things, and with all sorts of challenges. But I definitely think there’s a possibility of a cable bundle with streaming. It takes time to evolve.

Ex-Warner Bros. boss Sarnoff: It’s hard to understand the economics of how that will work. Can there be an aggregator so people wouldn’t have to subscribe to a bunch of different offerings? The problem is always who goes in the middle. That’s the thing: most media companies have wanted to move away from someone controlling their audience, like cable operators, and determining the value of the programming. Bundling makes sense from a consumer perspective, but as a supplier, it’s much more complicated. Paying one rate is simpler, but there’s an imperfect value equation in there for the content supplier/programmer.

Chernin Group’s Chernin: I don’t know. A full-blown stand-alone bundle is hard to do. There’s not an obvious aggregator who is going to benefit. Whose best interest is it to subsidize losses to bundle these things together? It’s pretty tough to figure out the economics. The big guys won’t want to take a discount. It would take very complex negotiations.

Mark Lazarus, NBCUniversal Television and Streaming chairman: I think bundles are definitely in the future. It’s sort of already headed in that direction. What’s not there is the ability to replicate the cable bundle user experience. It’s cumbersome, to have to go in and out of every app. It’s buffering. You can’t flip between any two channels, which is instantaneous. It needs to get to a point where the user interface or user experience lets you seamlessly enter or exit content if we’re going to live up to consumer expectations.

Starz’s Hirsch: Yes. In 18 to 24 months, you’ll start to see a repackaging of the linear business into the digital business. The value of aggregation is really important. You’ll start to see more people partnering up. Right now, everyone is seen as a channel. Ultimately, the big folks will become platforms, much like Amazon is doing today. The big guys are going to become platforms. You’re seeing it now with Showtime as a tile within Paramount+. Other companies’ content will become branded tiles within the larger streaming platforms.

Which companies will dominate as the main hub of streaming?

The Ringer’s Simmons: I believe Apple will be the dominant platform because of its connectivity to user behavior through Apple TV and our phones. They make it so goddamn easy; their main page allows you to order movies, see all the new releases, see where you left off on any show or movie you were watching on every other platform … it’s amazing. That’s the only streamer that acts like a one-stop shop for everything I care about. And they will get better and better at perfecting that. Plus, you can keep logging into your different platforms on there through your iPhone. It’s really smart. All roads lead through Apple.

Chernin Group’s Chernin: YouTube, Amazon and Apple.

Candle Media’s Mayer: There will be three categories. The cable guys could repackage streaming offerings. They’re already doing that with their linear offerings. You’ve got the telcos (T-Mobile, AT&T and Verizon), and then you’ve got the big digital players — Google, Apple and Amazon.

Starz’s Hirsch: You’re seeing Amazon become a platform, and Warner is now starting to become a platform. In the next three years, we’ll also see compression technology that will allow wireless companies to be true aggregators of streaming services — T-Mobile, AT&T and Verizon. They’ll become real challengers.

Charter’s Winfrey: There are a number of platforms — Roku, Apple TV and Amazon Fire — that are trying to aggregate streaming content. But I think cable has a real advantage. It’s what Comcast and Charter are putting together with our joint venture, Xumo. We will take the voice remote from Comcast, the technology assets from Sky and Xfinity, the leading live video app in Spectrum TV — you combine all that with the fact that Comcast and Charter have a much broader array of programming relationships than anyone else in the market. We also have a powerful distribution channel to deliver this operating platform, both to existing customers who pay for broadband and TV and new sales from our different sales channels — stores, platforms — to put these boxes and smart TV sets in customers’ hands. I think we have the best set of assets and existing relationships to be able to put it together that none of these other platforms can do.

LionTree’s Bourkoff: There hasn’t yet been an aggregator that has incorporated all of video, audio and gaming content — and we don’t foresee one anytime soon. That would be the beacon for consumers in their search for entertainment, in the broadest sense. Absent that, any other aggregation tool would have a different definition for different customers. For example, younger demographics are increasingly moving towards short-form content on TikTok, YouTube and other platforms. Would that be included? The definition of content we want to consume and where we consume it is always changing, particularly in a mature, scarce environment.

Entertainment Studios’ Allen: I don’t know if there will be a primary aggregator of this content, but I do believe the consumer is very smart and resourceful and will figure out how to get their needs met at a very efficient price. The key here is to look at the world’s biggest streamer, which is YouTube, and how it is completely free. Good luck putting something in that search bar and it doesn’t come up.

What happens to cable entertainment networks? Will they be sold? Shut down? Or will it look the same?

Paramount’s Chopra: I do think there’s the potential for additional consolidation of cable networks over time. I think in the near term, we’re going to see an evolution of the type and mix of programming you see on cable networks, given the audience declines in that area. The economics of producing expensive original content isn’t going to work for every cable network. They will have to look at different formats, relying on more lower-cost content, library content, etc., but it will definitely evolve.

Ex-Time Warner boss Bewkes: If you’re a network with news and sports, those can last. General entertainment network subscribers and cash flow will decline. Some might get sold to private equity to harvest cash flow in the three or four years. It’s not like they’ll go bankrupt, but they’re not good for public equity ownership.

Warner Bros. Discovery’s Finch: It’s hard for me to say because things seem to change so quickly in this industry. One of the most valuable things is a brand that stands for something. Brands really, really matter. A more generic cable network that lives on older content doesn’t necessarily offer something to someone on a nightly consistent basis. People don’t surf the way they used to. That’s not really how people are wired to watch content anymore. They come to a decision based on how they feel. So it’s true it is more challenging if you’re more of a general entertainment network. You need highly specialized content. Without it, you can’t survive or drive the kind of ad revenue that we can. When you have a HGTV you have endemic advertisers. If you’re Home Depot or Lowe’s, you have to be on HGTV.

Charter’s Winfrey: The question comes down to what is the value of the content they’re providing? If they’re providing reruns but you can’t find it elsewhere, then it still provides value to the customer. But what you have today is programmers selling us content at increasingly higher prices and asking us to distribute that to largely all of our customers, and at the same time, selling that exact same content either into streaming platforms or creating a direct-to-consumer product themselves at a much lower cost. And many of those services have a much lower security threshold than cable, so customers are able to share passwords and access the same content for free. So, our willingness to continue to fund that for programmers when that content is available for free elsewhere is declining. That means within the linear video construct, you’ll see an increasing number of distributors deciding it no longer makes sense to carry certain content, because customers are already can access it either for free in a pirated fashion or just paying for it at a lower rate.

NBCUniversal’s Lazarus: I don’t think it’s a one-size-fits-all strategy in the future. I think we’ll see some networks combine, like we’ve done. Some will close down that don’t make meaningful contributions to the bottom line. There’s so many networks today. Even with the erosion of the pay-TV bundle down to 50 million, these networks are still a meaningful contributor of revenue and EBITDA to companies like ours. So closing them isn’t necessarily a great answer because you’re giving up profit. Even if it’s a declining profit, it’s still profit. I think that part gets lost a bit in the conversation now. Yes, we are managing a decline and streamers are there to make up for lost revenue and profitability, but those businesses still kick off, in many cases, hundreds of millions of dollars in profit. Companies just don’t give that up.

What’s one thing that will become a TV standard that doesn’t exist today?

Chernin Group’s Chernin: Windowing. That’s the most likely change. Right now, the current economic model is two things: pure vertical integration, where you produce and own everything, and long-term exclusive licenses. Neither make sense. You can’t produce enough good content and it’s wildly overexpensive. What’s the value of 5- to 10-year-old shows? Right now, a huge amount of money is spent for those shows. Media companies would be better off doing three-year licenses and saving 20% to 30% on the cost. Cable networks will be interested in buying old reruns from other streaming platforms. It’ll be brand-new programming to a different audience. What defines programming is what’s new. When “Sopranos” aired in syndication on A&E, it’s didn’t make HBO any weaker. You’ll see streamers start selling programming to cable and to one another, and it will produce value both to the company that owned it and the company that bought it in syndication.

The Ringer’s Simmons: I believe Apple, out of nowhere, will start making their own awesome televisions that have Apple TV embedded in them. It’s kind of incredible that this hasn’t happened yet. They have every other piece of the streaming puzzle in place — literally, all of it — except for the actual TV. Why would they want Samsung, LG and whomever else to keep innovating on their smart TVs and eventually cut Apple out of the entire ecosystem? They’ll just make a better TV and crush them. I wish I could bet on this.

Ex-Warner Bros. boss Sarnoff: A “metaverse” which offers commerce, gaming, social interaction, sports, news and entertainment is inevitable, but I think we’re quite a ways from that being the primary way people consume media. It will be interesting to watch the metaverse evolve in parallel to streaming and other direct entertainment offerings. The offering that best engages and entertains the consumer will win.

Ex-CNN boss Zucker: The ability to bet and/or gamble while you’re watching sports on TV will be much easier. You’ll be able to go through the TV to place a bet with a remote control, or your voice. It requires partnership from the betting companies, but that shouldn’t be a problem.

Starz’s Hirsch: Content without borders. Artificial intelligence technology will make subbing and dubbing of content simple. AI will allow you to watch content in your home language without a third-party dubbing it for you. The world shrinks that way from a content perspective.

Netflix’s Bajaria: More people will have access to incredible global stories on demand. The average person will gain access to more content than ever before.

Entertainment Studios’ Allen: I think we’re going to see more AI integrated into content, and it’s going to be more intuitive, so when people watch the content it’ll be far more advanced in recommending content for you. I think AI is going to help understand the touch points in content and how to make it better and more compelling and engaging.

Charter’s Winfrey: Unified search. You’ll have a discovery and recommendation engine combined with a voice remote that allows for a seamless experience for the customer living inside a single platform. That will allow a viewer to pick and choose what content they want month to month — either live video or streaming.

LionTree’s Bourkoff: Sports is being unlocked in a big way. It’s the last major bastion of content that must be watched live, which begs a different approach. As owners of valuable IP, professional sports leagues may increasingly go direct, either on their own or via a partnership model, and monetize in other ways — from advertising and sponsorships to commerce and experiences, including gaming and sports betting. We are witnessing early stages of this dynamic with deals like “NFL Sunday Ticket” on YouTube and the MLS deal with Apple TV.

Warner Bros. Discovery’s Finch: There is something that is beginning to exist now that I’m absolutely fascinated to see where it goes. It’s the technology that allows viewers to choose the content they watch as they are watching. Like the Netflix show “Kaleidoscope.” Handing the editorial decision-making to fans is so seductive. It’s an opportunity for a piece of content to be watched multiple times. There’s just a few pieces of content that’s tried this, but the technology is there, and it’s an exciting new development in content creation and consumption. It gives the audience an interactive way to view these things. It’s just beginning to be utilized and a lot of people are experimenting.

NBCUniversal’s Lazarus: Much of TV consumption is being done on the biggest, best screen in your home. It’s all coming through your living room flat-screen TV. What we see, and I think will change over the next three years, is the amount of customization people are able to have to curate their own abilities and to bundle themselves. How do you order your streaming apps? While it’s not a seamless user experience to go between Peacock and Netflix or something else, you can place them in whatever order you want on the screen. The degree of customization is there. That’s coming to the individual streamers, too. We’re working on a lot of customization for our consumers. Consumers would like to have that interactivity. If you’re on a live sports channel, you can curate your own replays and then bounce back to live. It’s the next iteration of interactivity.
