The number of UK fixed-line broadband connections increased by 941,000 during 2013, it has been reported.
Latest figures published by media regulator Ofcom reveal there were 22.58 million individual subscriptions at the end of last year, excluding corporate lines.
ADSL's share of the market declined, as many homeowners and small business customers replaced their copper-based broadband connections with super-fast fibre.
At the end of last year, there were a total of 9.24 million ADSL lines which use local loop unbundling (LLU), plus 6.58 million non-LLU lines.
The previous year, there were 8.78 million LLU ADSL lines and 7.47 million non-LLU ADSL connections.
2013 saw a slight rise in the number of cable broadband subscribers, as more households and small businesses signed up with Virgin Media.
At the turn of the year there were 4.39 million cable broadband customers in the UK, up from 4.29 million.
The number of fibre broadband customers increased from 1.10 million to 2.36 million over the 12-month period.
