Ad network Collective Media just landed another big fish: a $20 million second funding round. Not bad for a down ad market. The New York Based firm has also climbed from the 21st largest ad net to the 19th over the last year, according to comScore’s numbers.

Collective Media serves leading brand advertisers on the Web’s highest traffic sites. It has also invested in proprietary tools to improve contextual relevance and target according to demographics, behavior, and the like.

As VentureBeat explains, the ad net “focuses on unsold or unreserved ad space (the industry’s dreaded term is “remnant”) and competes in that arena with the big three ad networks: Yahoo, AOL’s Platform A, and Microsoft Media Network.” The company plans to put the new capital towards strategic growth and tech development; the funding will also support possible acquisitions along the line of last year’s purchase of semantic technology firm Personifi.
