In December, a month in which 62 percent of Americans are planning to support charities for the Holiday season, The Daily Beast undertook an extensive study on the effects of celebrity on charities. Looking at the 50 biggest celebrities allied with a nonprofit, either as a member of its board or advisory committee, an ambassador, or the face of a campaign, The Daily Beast tallied how much awareness they produced for their favored nonprofit in print, television, and online, and also calculated any personal donations to the charity, since cash is the most direct impact of all.
Using VMS and BurellesLuce, media-monitoring firms, along with Lexis-Nexis and Google search results, The Daily Beast compiled and attributed value to media mentions.
