Teens still watch TV – http://www.advanced-television.com/2009/dec7_dec11.htm#w2
Based on a Europe-wide survey of nearly 1,400 internet users aged 12-17 across seven major territories (UK, France, Germany, Italy, Spain, The Netherlands and Sweden), Forrester captured a number of key teen consumer trends:
—TV is still the main media channel for teens.
Reports of TV’s death have been greatly exaggerated. European teens still spend more time watching TV (10.3 hours per week on average) than they do using the Internet for personal purposes (9.1 hours). But gaming – 11.7 hours per week if you combine time spent playing games on a PC and on a console – now consumes even more time than TV for European teens.
—Social interaction online is an integral part of media consumption.
European teens have embraced social media – not only Facebook, which 44 per cent visit at least weekly, but blogs, which 30 percent read at least weekly.
—Multi-tasking is mainstream.
Content providers need to understand that for most teen users, content is rarely consumed in isolation on one platform. The vast majority of internet using European teens do something else while online – 50 per cent listen to music on the PC, while 45 per cent watch TV while online, for example.

There was also a recent study (June 2010) in Finland regarding the TV watching habits – and it showed the same.
From January to May 2010 the Finns watched linear TV on average 3 hours and 15 minutes per day, which was 3% more than in 2009.
The most surprising was that the biggest growth was in the age group of 15-24 years old, who spent 1,5 hours more time per week on front of the TV than in 2009.
The share of the time-shifted watching through PVR was 5% from all the the time consumed with TV – it remained the same.
