From the Economist:
DESPITE an increase in entertainment choices, watching television remains as popular as ever, according to the OECD’s “Communications Outlook 2007”. In 15 of the 18 countries for which data were collected, broadcast-TV viewing increased from 1997 to 2005. Only in Spain, New Zealand and South Korea did people watch less. America takes the couch-potato crown, with households goggling at the box for an eye-straining average of 8 hours and 11 minutes every day. The nearest rival, Turkey, only manages an average of five hours a day.
It would also be interesting to know how many people are online while they watch TV. It’s hard to get people to pay attention when their is so much media coming at them.
