Most mobile telephone users in the United States have a chance to participate directly in America Rocks the Vote, a Nov. 4 Democratic presidential candidate forum.

For America Rocks the Vote, CNN enlisted the services of all major carriers and four regional carriers to support text messaging for the presidential forum. The cooperation with the carriers means that about 130 million cellphone users in the United States, or 90 percent of the total market, will have the ability to interact with the broadcast.

"We believe that CNN is the first major news network to integrate such services into its television broadcasts and that this will be one of the widest distributions for any text messaging initiative ever run in the United States," said Mitch Gelman, senior vice president and executive producer of CNN.com

The participating carriers are AT&T Wireless, Alltel, Cincinnati Bell, Cingular, Cricket, Dobson, Nextel, Sprint PCS, T-Mobile and Verizon.

The text messaging service for the presidential forum marks one of CNN's first efforts to highlight its improved CNNtoGO wireless services. CNN relaunched CNNtoGO on Monday, Oct. 20, to include text messaging, mobile polling and access to CNN.com's up-to-the-minute news coverage and full-color images.

CNN, a division of Turner Broadcasting System Inc., a Time Warner Company, is one of the world's most respected and trusted sources for news and information. Its reach extends to 16 cable and satellite television networks; two private place-based networks; two radio networks; wireless devices around the world; nine Web sites, including CNN.com, the first major news and information Web site; and CNN Newsource, the world's most extensively syndicated news service.
