The proportion of internet users in Britain spending more than five hours per week online has more than doubled in the past 10 years, from 25% in 1998 to 58% in 2008, according to a new report.
It found that while three quarters of internet users (75%) spent less than six hours online ten years ago, this has dropped to only 42% in 2008.
Social networking online is also increasingly becoming the norm, with 25% of internet users interacting with these sites in 2008.
Listening to the radio via the internet is a popular activity, with 27% of those online doing this, while 14% use it for gaming.
Podcasts have yet to hit the mainstream, with only 8% of people using them and just 2% engage with online communities such as Second Life.
In February eMarketer predicted that 42.8 million Britons will go online in 2012, accounting for about 70% of the population (see 70% Of UK Will Go Online In 2012).
