SplashCast, a startup that lets you create your own broadcasting channel, has announced that it has successfully secured $4M in Series A funding.

While the company once hyped the idea of injecting social networking into podcasting, now its focus is “a new form of online marketing called social advertisements.” According to the compan, their social advertisements consistently receive click-through-rates 75 times higher than typical banner advertisements used on MySpace, Facebook, and other social network sites.

“It’s clear that Internet sites such as MySpace and Facebook are the new TVs for today’s young consumers and that SplashCast is far and away the best tool out there for reaching this audience,” said Bayliss. 

SplashCasts are like multi-channel TV screens that can be placed on an individual’s social network profile page. Brands and media companies can use SplashCast to distribute videos, games, pictures, and other digital content. You can share SplashCasts so that others can embed them in their MySpace or Facebook pages.
