President Barack Obama is turning to MTV to get young people to tune in for his speech at the Democratic Party's national convention.

Obama's campaign is running a television ad Thursday night at the end of the cable channel's annual movie awards show. It will air just minutes before the president is to speak.

The ad is titled "Gotta Tune In" and encourages viewers to switch channels and watch the president accept his party's nomination.

Obama is scheduled to speak during the 10 o'clock hour in the Eastern time zone.

Obama's advantage with young people propelled him to victory in 2008. His campaign is seeking to maintain high levels of support among younger voters, even as they face an uncertain economy and shaky market.
