Of those with presence on social networking sites, 30 per cent visit them several times a day. And nearly half of cellular phone owners text several times daily.
For the first time, the Arbitron/Edison research discovered Americans preferred the Internet to television as the "most essential" platform in their lives.
The report confirms the younger skew in social networking --- three-quarters of those under 24 have some sort of account. But it also indicates social networking is expanding into older age groups --- half of those 35 to 44 have a presence in social media.
