Mobile apps are exploding across all platforms, and venture capitalists are getting increasingly selective about which companies and services they’ll back.

That’s the upshot of a panel at the AppNation conference taking place in San Francisco this week, just a few weeks before Billboard hosts its own Music App Summit there Oct. 5.

“It’s getting Darwinian out there. The bar is rising,” said Matt Murphy, a partner at Kleiner Perkins Caufield & Byers, according to a report in the Wall Street Journal. The “me-too” companies are getting less attention, while the new innovators are getting more attention even if they have fewer numbers.

That’s because VCs want to bet on companies early, so long as they show potential and the ability to create a new market. And while the iPhone has been the attention-getting platform to date, focus is turning to the surging Android system.

Murphy will be a keynote speaker at Mobile Entertainment Live: The Music App Summit, taking place Oct. 5 in San Francisco . For details and to register, visit
