Ofcom's latest Communications Market Report reveals that the growing adoption of smartphones and tablets in the UK is changing the way people communicate and live their lives.
Alongside observing that Britons are now communicating more by text message than making phone calls, Ofcom also identified a number of other notable new trends in people's behaviour.
Four in ten (39%) UK adults now own a smartphone, up 12 percentage points on 2010, and 42% of these people say that their mobile is the most important device they have for accessing the internet.
Over half of smartphone users claim to use their phone in some way when out shopping, such as taking photos of products (31%), making online price comparisons (25%), scanning bar codes to get more product information (21%), reading online product reviews (19%) and researching product features (19%).
Alongside smartphones, tablet ownership is also starting to take off in the UK, with products such as Apple's iPad and Samsung's Galaxy Tab helping to increase tablet ownership from just 2% in Q1 2011 to 11% in the same period this year.
This growth is expected to continue as 17% of Ofcom's respondents said that they intended to buy a tablet in the next year. But despite the portability of tablets, nine in ten slate users said that they mainly use their device at home.
Alongside tablets and smartphones, another device growing in popularity is the smart TV, which connects to the internet to offer web services and video on-demand alongside television pictures.
Despite nearly half (47%) of smart TV owners being initially ambivalent about the new internet capabilities of their set, over two thirds (65%) claim to have later embraced the chance to 'turf' from their sofa.
The trend is also leading to a growth in popularity of larger TVs, with more than two thirds of sets sold in the UK in Q1 2012 being either 'super-large' (33-inch to 42-inch) or 'jumbo' sized (43-inch and over). This compares with just 1% of TVs of these sizes that were sold in 2001.
Elsewhere in the report, it was revealed that UK viewers watched on average four hours of TV per day in 2011, roughly around the same as in 2010, but up from 3.7 hours in 2004.
Over a third (37%) of UK adults with home internet watch online catch-up TV from the likes of BBC iPlayer or 4oD. Over half (51%) of those with a smart TV said that they had watched on-demand TV.
Total UK television industry revenue increased by 4.9% year-on-year in 2011 to reach £12.3 billion. Ofcom said that this was driven by an increase in pay-TV subscriptions (up 8.3%) and television advertising (up 2.1%).
Eight out of ten people in the UK had access to the internet in Q1 2012, with the biggest increase seen among 65- to 74-year-olds, up nine percentage points to 64%.
People on average spent 23 and a half hours online per month in 2011, and two-thirds of UK internet users have accessed the now-listed social network Facebook.
