Rocketboom is going mainstream.

The seminal newsy video blog, launched in October 2004, signed a reported seven-figure deal with Sony Pictures Television to distribute Rocketboom on Sony’s Crackle video site and across other Sony platforms such as the PlayStation 3, the PlayStation Portable, and Bravia I-Link televisions.

Sony also will handle all of Rocketboom’s ad sales, which is a load off Andrew Baron’s mind. Baron, the founder and producer of Rocketboom, said in an entry on his personal blog that dealing with advertising, while “fun to play,” was distracting as “every moment we spent on ads was a moment lost on the content.”

Baron’s blog post is a must-read as it gives a glimpse into what life has been like for Rocketboom the past three years. Not only is there content generation needs — from commenting on mainstream news to Internet culture and everything in between — but there’s the pesky business side, which most new media ventures struggle with. How do they make money?
