The BBC will allow mobile iPlayer users to download programs to mobile devices for the first time.
From Tuesday, the mobile iPlayer app for the iPhone, iPad and iPod Touch will include the ability to save programmes for up to 30 days.
Users will be able to watch a programme at any time in that period, but once started will only have seven days to finish it.
The new features will be coming to Android apps soon, the BBC said.
"With mobile downloads for BBC iPlayer, you can now load up your mobile phone or tablet with hours and hours of BBC television programmes, then watch them on the road, on the Tube, on a plane, without worrying about having an internet connection or running up a mobile data bill," said Daniel Danker, general manager of programmes for the BBC.
The Beed added that there were about 30m requests for iPlayer programmes on mobile devices in August alone.
