Surfing the internet, playing games and hanging out on social networks are
important for teen development, a large study of online use has revealed.
The report counters the stereotypical view held by many parents and teachers
that such activity is a waste of time.
More than 800 teenagers and parents took part in the three-year US project.
"They are learning the technological skills and literacy needed for the contemporary
world," said the report's author, Dr Mimi Ito.
"They are learning how to communicate online, craft a public identity, create a
home page, post links.
"All these things were regarded as sophisticated 10 years ago but young people today take them for granted," Dr Ito told the BBC.
