Looking at the title of your thread, would it be beneficial to whom? Your idea is counter to the trend of what's happening and has been for some time. Media companies are actively moving content OFF their OTA signals and away from their cable channels and placing it exclusively on their paid streaming platforms. When watching the Food Network, HGTV or any number of other channels that are owned by Discovery, one often sees plugs for some really interesting and attractive (at least in my opinion) content...Followed by the message that it's ONLY available with a subscription to Discovery+. You can't get it with a cable or Dish subscription, even if that comes with on-demand. Same goes for Paramount, Universal, Netfix, Amazon, Apple and a whole host of other streamers.
When overhearing people talk about the shows they're really into or what they're telling others they NEED to watch, it's often something only available on a streaming platform..And it's where a lot of folks, especially younger demographics, are happy to view the content they're most interested in. Even sporting events, college, pro and otherwise, are now at times only available via streaming.
Conversely, many are cutting the cord and moving away from cable. In many cases it's become prohibitively expensive, especially for those who only watch a small handful of channels or programs that they can stream for much less than the price of a cable subscription that gives them at least several hundred channels full of stuff they have no interest in and will likely never watch. Adding yet more content that many will still never watch, won't help lure anyone back to cable.
