Digital television is watched in nearly two thirds of UK homes, broadcast watchdog Ofcom has found.
The analogue TV signal will be switched off between 2008-2012
The number watching digital TV has risen to 65.9% - representing 16.5 million households. This was an increase of 2.9% since June.
Digital TV is accessed through existing TV aerials, or through satellite, cable and television-over-broadband services.
Over one million Freeview boxes, which pick up signals using existing aerials, were sold from July to September.
Cost of switching
Sky added 48,000 subscribers to its digital satellite service in that time, bringing its number of UK subscribers to 7,472,000.
Digital cable subscribers increased by more than 43,300.
The analogue TV signal will be switched off, region by region, between 2008-2012.
Ofcom estimated the cost of switching to digital would be £132 per household. There will be government help for those aged 75 and over as well as those with disabilities.
