Traffic Marketplace, a Los Angeles-based ad network, has acquired fbExchange, an ad network focusing on Facebook and social media applications, for an undisclosed amount of money. TMP is going to use fbExchange to diversify its online advertising business to social networks. I first wrote about fbExchange back in 2007. It’s the brainchild of 83Degrees, a San Francisco-based idea factory started by Narendra Rocherolle, Julie Davidson and Nick Wilder. The trio are also co-founders of Webshots and 30Boxes.

“For us, our business is about exploring new ideas and growing them until they find a good home,” said Rocherolle when I reached him for a comment. Another Facebook-oriented advertising network, Lookery, which launched during the early days of the Facebook App Mania, sold off its advertising network and has refocused its business, too.
