Ofcoms’ latest report shows that 87.6% of households in the UK have “multi-channel TV” meaning access to more than just the terrestrial channels.
More than 22 million households now have digital television on their main TV set.
According to the research, 524,500 households signed up to digital in the last quarter up to December, while more than 280,000 households went for digital cable and satellite platforms.
Cable TV has now overtaken analogue terrestrial to become the third largest platform - behind digital terrestrial and pay satellite - for the first time, with nearly 3.5 million customers and a 13.6% share of the television market.
It says that almost 75% of TVs sold in the fourth quarter of 2007 were IDTVs.
The UK is set to switch over to digital in 2012.
