"The Batman OnStar commercials were a series of six television commercials featuring comic book superhero Batman, created by ad-agency Campbell-Ewald and aired from 2000 to the beginning of 2002. In 2000, OnStar, DC Comics and Warner Bros. teamed up to promote brand name awareness of the new OnStar onboard guiding system, leading to a large increase in subscribers and a higher rate of subscriber renewals."@en . . .
