That's the objective of Paul Graham's drive to fund alternative entertainment startups:
There will be several answers, ranging from new ways to produce and distribute shows, through new media (e.g. games) that look a lot like shows but are more interactive, to things (e.g. social sites and apps) that have little in common with movies and TV except competing with them for finite audience attention. Some of the best ideas may initially look like they're serving the movie and TV industries. Microsoft seemed like a technology supplier to IBM before eating their lunch, and Google did the same thing to Yahoo.
Alyssa Rosenberg thinks he's dreaming:
I don’t know that there’s good evidence that there will be a direct tradeoff between movie spending and other forms of entertaining. Video game sales are outstripping movie tickets, but it’s not like movie ticket sales have declined in relation to the rise of video games: in fact, both industries have experienced a similar downturn in the recession. And certainly, video game creators have an interest in Hollywood surviving as a way to spin off games into movies that help extend and make more durable existing franchises. There may be new forms of entertainment in 50 years, but I’m not sure it’s going to entirely replace movies or television, both of which have proven to be durable art forms even as our ways of consuming them change, posing both distribution and storytelling challenges. I don’t doubt that we’ll get new and exciting forms of entertainment. But I don’t think we’ll have to kill Hollywood to get them.
