Forbes.com has launched the Forbes Audience Network, an online advertising network the company hopes will be attract 20 million unique visitors. The network provides marketers with a number of services including mass reach, targeted impressions and editorial compatibility, the company says.

"As ad networks go, none deliver the reach, brand association, targeting and quality environment that the Forbes Audience Network offers," Forbes.com vice president and managing director Bill Flatley said in a statement. The sites in the network include Forbes.com, ForbesTraveler.com, ForbesAutos.com, Investopedia.com, RealClearPolitics.com and Clipmarks.com.

Earlier this month, Forbes Media purchased the majority share of RealClearPolitics.com, an aggregator of political news, and purchased Clipmarks.com, a service that allows users to clip portions of content online. The company purchased investor education Web site Investopedia.com in April.

"These properties offer an unprecedented combination of business and financial news, luxury travel and automotive expertise, investing education, political savvy and innovative online tools to our affluent audience," said Forbes.com president and CEO Jim Spanfeller.
