A fifth of U.S. adults have engaged in video chats

The study, which surveyed 3,001 people over the summer, found that 74 percent of American adults use the Internet. And out of that group, 23 percent of folks have tried video calls, chats, or teleconferences over the Web.

In the study it was the first time that the Pew Research Center's Internet & American Life Project asked about the use of video calling online and via cell phones.
