The BBC's iPlayer will be available directly to Sky viewers after the broadcasters signed a deal to work together.
It will be added to Sky's Anytime+ catch-up service later this year and will be available on the televisions of around five million Sky customers.
BBC director general Mark Thompson said: "Having the BBC and Sky work together to further build on the BBC iPlayer success story can only be fantastic news for audiences.
"Making BBC iPlayer available on all platforms is key to our commitment to universal access and this agreement takes us one step further towards that goal.
"I'm delighted to take this first step on a story of innovation for both organisations."
The iPlayer, which was launched in 2007, can already be accessed on internet-connected TVs, computers and mobile phones.
