Hollywood’s majors need to update their MySpace pages if they want to reach younger moviegoers.

MySpace is the top online destination for 15- to 24-year-olds looking for information about new film releases, according to a study by Nielsen NRG.

In that prime moviegoing demo, the News Corp.-owned social networking site beat out rivals, with 29% of those surveyed saying they use MySpace first to search for movie info. Yahoo and Google were a close second with 23%, while AOL trailed with 14%.

Some 46% of 15- to 24-year-olds who viewed film information or ads online saw the material on MySpace vs. 26% on Yahoo, 18% on Fandango and 12% on AOL’s Moviefone.

Study focused on 13 summer releases, including “The Dark Knight,” “Get Smart,” “Forgetting Sarah Marshall,” “Step Up 2: The Streets,” “300,” “John Tucker Must Die” and “The Omen,” which bowed over the past two years. Nearly 42% of those who took part in the survey said they saw ads for the pics on MySpace.

Survey also found that the Internet beat out TV as the main source for information on Warner Bros.’ “The Dark Knight,” which launched an extensive online campaign for the Batman sequel.

Nearly 70% of the more than 11,000 individuals surveyed in the 15-24 age bracket said they have an active profile on MySpace.
