Broadband uptake in the UK remained strong in 2009 despite the global economic downturn and recession.
New research from Ofcom has shown that internet service providers had more than 18 million broadband internet subscribers on their books at the end of last year.
According to the organisation's Telecommunications Market Data Tables Q4-2009, this amounts to almost one million more UK broadband subscribers than there were in 2008.
Compared to the third quarter of 2009, the number of residential and small and medium-sized enterprise broadband connections in quarter-four increased by 317,000.
Ofcom's report said: "BT continued to be the largest residential and SME broadband supplier during the quarter, with its market share unchanged at 26.7 per cent."
According to other research conducted by the UK communications regulator, British broadband users are becoming more security-savvy.
Ofcom's Media Literacy report also showed that more UK broadband users are checking their bank balances online than ever before.
