I've read a few articles that claim a large part of the reason ATSC 3.0 is supported by broadcasters is the potential money to be made from marketing. All information about what you watch, and any personal details stored in the box, will be totally available to broadcasters. Supposedly they will be able to change the commercials shown to each viewer based on your information they get from the box. If your box has a dvr function they will able to change and update the commercials in any programs you have recorded. DRM is broadcasters way of finding more ways to sell people items or services they don't need or want.

Not ATSC 3.0 channels. People very far from large urban areas don't have many channels to choose from.

I grew bored with Television over 4 years ago, I bought a 86" Tv 4 years ago also and I've never cared enough to take it out of it's box. If I get bored enough I'll watch something using free streaming services. I just buy physical discs of anything I might want to watch. Friends tried to get me to watch football and other sports but it's just too boring. I know the rules but it's just people chasing a ball back and forth. To enjoy sports you have to care who wins, and I don't care, who wins or loses means nothing to me.
