—Delivering a “black” Google: The trend towards niche sites and networks that are more tightly focused on specific groups is increasing as online ad growth has slowed and behavioral targeting is under siege from lawmakers and regulators. Sites devoted to women or minorities helps advertisers target safely and fills a need for audiences themselves. Some of the major companies that have either formed or given an added push to its black-oriented content recently include the partnership between Time Warner (NYSE: TWX) siblings Essence.com and WBTVG on a new broadband destination and website revamp, and IAC’s (NSDQ: IACI) RushmoreDrive, a search and news site that was unveiled in April. Last month, Johnny C. Taylor, the president and CEO of RushmoreDrive, told LAT that the IAC site serves as a “black Google” because its search functions gives links that might interest African-Americans more weight. In keeping with that, RushmoreDrive is developing a new “identity search” site by Q209. RushmoreDrive’s traffic hit 800,000 uniques this summer.
