Kind of want reply both to you and @pjc50:
I think moving images with sound as part of hypertext/hypermedia is a given -- and has been since (at least) the 60s. That's not just "TV". And "TV" isn't just video.
We've only recently entered the era where users can reasonably make live and recorded video, and use that as a form of expression (from video chat, to youtube/vimeo to snapchat etc). And just like you could take a tv camera and use that for video conferencing in the 60s[1] -- video-the-medium is much more than "TV".
"TV" is indeed very pacifying. For myself, I can on days off, do two very different things that are very immersive: watch tv series, or play Star Wars: Online Galaxies. Now, I mostly play SWTOR solo, so for the purpose of this discussion, lets just use "play a single-player computer game". I enjoy both, but if I read a book or play a computer game -- I'm mentally invigorated. If I watch a TV series, even something interesting like "Humans"[h], "Mr. Robot"[r] -- or more interesting drama like "True Detective"[t] -- I always end up more passive. Even watching documentaries, or news -- TV ends up a very passive medium.
And that's (IMNHO) just the good "TV". I find that a good movie is usually between "book" and "TV" -- something with the format/runtime that drives a different expression both in writing and directing.
> We've been trending away from the 'web as a collection of books' to 'the web as a series of TV channels' for many years now.
I don't think the web has ever been much like a "collection of books". It might have been "a collection of essays" -- and I don't think we're really trending towards "a series of TV channels". I think we'll still see video expression and communication evolve, and I think user generated communiques ("content" is more something that oozes from a (corporate) organization) will continue to dominate.
It is my impression that young people (~3-20) are much more inclined to use video than I am -- I don't much like it. But I expect rich media images/sound/video will continue to increase, as bandwidth/storage gets cheaper.
I think that trend in media is different from the trend in centralization, commercialization though. There's nothing wrong with videologs (other than that I prefer a well-written text...) -- as long as we can host them in a more distributed manner than we do today.
I think we'll see interesting times ahead, as the people that are now 5 years old grow up to master both rich media and various forms of programming/automation as a natural part of their life. We've seen nothing yet. Nothing.
A post-script on quality: I think many of us want quality. And I think we'll continue to make it, and find it. Be that small Internet radio-stations that do curated music (as opposed to things like soundcloud that I also like, but unfortunately is just as hopelessly centralized as youtube) -- or "real" blogs -- or whatever.
It remains to be seen how/if this will all be funded. Maybe we won't have as much paid-for content/art -- maybe we'll all have more free time -- assuming we don't kill each others as jobs are automated away, and those who own the robots keep all the riches.
