And why would game companies want to kill streaming? It's free advertising, not to mention that they all probably dream of making the next dota.
Never underestimate the power of human greed. Apple (with iTunes) has proved that the availability of unprotected content doesn't hurt the bottom line, and when I go into a store today and buy a physical CD-ROM it more often than not lacks any copy protection. And this has been the situation for years.
Meanwhile, the movie industry is soundly asleep at the wheel and its execs don't recognize that the consumer demands (near-instant access, no copy protection, no unskippable FBI warnings, no unskippable teasers, and no freaking region lock) have greatly diverged from their offerings. Or they do recognize, but cannot change their existing contracts or whatever - in this case the entire industry deserves a burn-to-the-ground event, because the situation ain't going to be fixed otherwise.
And for the game companies: there are already companies taking down "let's play" videos. Need for "absolute control", I guess. And they still haven't stopped putting retarded DRM (including what basically amounts to rootkits, in the form of anti-cheat stuff) into their games.
Are you implying that people still use DVDs or Blu-rays?
If you are, I got genuinely curious, because in Brazil at least, I'm quite certain they got nearly extinct. Here, is Netflix, cable (or satellite), online "channels" as HBO-Go or torrent.
Based on that, it appears to me that consumer demands already won.
