Even the gaming industry will go through further shifts in their business models - they're just occurring faster and the industry responding faster.
The cost and availability of tools to do the job (programming, art, music, video, animation etc) are decreasing and increasing, respectively, as is the quality of what they can do. "Fans" are creating extra content that, in some cases (IMHO) equals or surpasses what the massive publishers are doing. (This goes for music, art, photography, etc these days too.)
The movie industry has developed such bloated costs that they're dependent on the next big "fad" that requires people to come to theaters. Historically it took a fair while to get quality movies for each of the new movie eras (silent/talkies (bw with sound)/colour/special effects/and now 3d). TV, the VCR etc, didn't kill movies in the theater, just crappy movies in the theater. Now, with more exceptions, most people I know only go to a movie in the theater because it provides an arguably better experience (big special effects/action movies....maybe 3d?). At some point, I really hope, the floor will burst and the high salaries demanded, profits, etc, will change to "reasonable" again and the theater business will have a hope in hell of surviving. (ok, that was a ramble...sorry!
