New York ? Consumers’ appetite for high-speed Internet access and the online activities associated with it is growing, recent surveys show.

Roughly 24 million Americans, or 21 percent of all Web users, now have high-speed connections at home, an increase of more than a quarter since the start of the year, and quadruple the number of broadband users just two years ago, according to a survey conducted last month by Pew Internet and American Life Project.

“This places broadband adoption rates on par with the adoption of other popular technologies, such as the personal computer and the compact disc player, and faster than color TV and the VCR,” said researchers for Pew, a nonprofit initiative of the Pew Research Center for People and the Press.

Nearly six in 10 broadband users have generated their own online content such as a personal Web page, posted information to a Web site or shared music and other types of files online, according to a survey of 507 adults with high-speed service conducted in January and February.
