Silicon Valley and Hollywood: What's behind their growing love fest

"Silicon Valley and Hollywood are now joined at the hip," says Bill Baker, co-founder and CEO of the Celebrity Food Network, based in Southern California.

Why now? Tech billionaires who've become overnight celebrities; Hollywood's star-making culture seeking to exploit that fame; and the sheer preponderance of tech in our lives, starting with the smartphones most of us are now glued to. And Hollywood, Baker says, is being powered by cutting-edge technology like never before. "The new kinds of cameras, the digital-editing machines, the fiber, the satellites," he says. "These are the guts of what Hollywood does, and a lot of it comes from the tech world. So you have this mutually symbiotic relationship."

The ensuing confluence can be dizzying as valley companies create their own shows instead of just offering entertainment produced in by others.
