The Pew Internet and American Life Project (and if that isn't a pretentious name for an ongoing research project, I don't know what is) concludes that television is on the outs as an information applicance and the landline telephone is becoming less relevant as a communication tool, particularly for people in their 20s. The Internet is supplanting the TV and landline phone in its traditional roles, Pew says.
"Although only 2% of all Americans have cancelled a wireline phone since getting a cell phone, 7% of the most enthusiastic tech users have done this," the Pew folks reports. "Another 20% have seriously considered doing so."
