CityGrid Media Buys BuzzLabs

West Hollywood-based CityGrid Media, the unit of IAC formerly known as CitySearch, said today that it has acquired BuzzLabs, a social media monitoring and sentiment analysis software developer. Financial terms of the deal were not announced. CityGrid said the buy would help it aggregate and analyze millions of pieces of content across its network, and provide that data to its publishers and merchants. The company explained that it would be integrating BuzzLabs' technology into its platform over the next three to six months. BuzzLabs was based in Seattle. CityGrid Media operates the Citysearch, Insider Pages and Urbanspoon web sites.
