"We see a deep amount of engagement from teens on this campaign," says David DeLuca, Head of Campaigns at DoSomething.org. "They take the time to stage creative and fun anti-texting and driving scenes with their friends and the thumb socks. We get amazing and hilarious photos. This campaign is about friends having fun together while sharing an important message."Star of HBO's The Newsroom, Olivia Munn, lends her talents for the Thumb Wars PSA this year, making the issue accessible and relatable for teens. Other celebrity supporters include funnymen Joel McHale and Ken Jeong, who started a thumb war in honor of 2010's inaugural campaign, and Glee heartthrob Harry Shum Jr. who supported the campaign in 2012 with his good looks and dance moves.
