(Nasdaq: VCLK) and the leading global provider of affiliate marketing solutions, today announced a record number of new clients as the company kicks off its Commission Junction University (CJU) networking and educational event taking place this week in Santa Barbara, California. As the affiliate marketing industry's premier networking and educational event, CJU brings together more than 700 affiliate publishers and marketers with nationally prominent brands.

Among the marketers in attendance at CJU will be some of the new clients who joined the Commission Junction affiliate network in the first half of the year through June 30, 2008.

According to Michael Stromer, Director of Interactive Marketing at JetBlue Airways, "We selected Commission Junction as our affiliate marketing provider of choice because of their wealth of knowledge and experience working with best-in-class marketers in this space, their exceptional account management team and their attentiveness to their partners' individual needs."
