TalkTalk TV attracts 12,000 extra households each week as word gets around of what YouView has to offer.
YouView is helping to make TalkTalk one of Britain's leading digital TV providers.
Almost a quarter of a million UK homes have a YouView box supplying TalkTalk TV, with more than 150,000 new households joining in the first three months of this year alone.
According to TalkTalk's own research, three-quarters of homes taking a YouView box - free of charge with broadband and home phone bundles - are upgrading from Freeview.
Dido Harding, chief executive of TalkTalk, said: "We have the UK's fastest growing TV service and our customers clearly appreciate that it's great value for money."
She predicts that TalkTalk TV will eventually attract three-quarters of TalkTalk's four million phone and broadband customers.
TalkTalk launched its YouView service at the end of September 2012, offering customers a digital TV box worth around £300 at no extra cost.
With a YouView box, viewers can pause, rewind and record TV shows from 70 channels, as well as being able to watch seven-day catch-up when the box is connected to broadband.
In addition, TalkTalk TV has a range of premium, on-demand content, including pay-per-view access to the LOVEFiLM Box Office library, with recent blockbusters like The Hobbit and Life of Pi available to rent from just £2.50.
YouView is also offered by BT as part of a TV, broadband and phone bundle. Or customers can purchase the standalone box from high street retailers like Argos and John Lewis, but this would mean paying the full price upfront.
