The deal covers more than 260 hours of content, from Gerry Anderson's 1960s classic 'Captain Scarlet' to the James Nesbitt and Helen Baxendale-starring comedy drama 'Cold Feet', which started in 1997.
Dawn Airey, managing director of ITV Global Content, said: "We want to give viewers the opportunity to watch their favourite shows wherever they are. ITV has thousands of hours of classic content in the archive which we are bringing to a whole new audience via iTunes.
"Our strategy is to deliver 360-degree value for our content on multiple platforms, and in multiple territories, and our partnership with Apple is a demonstration that we are delivering on that strategy."
The deal was brokered by Steve Gallant, publishing director at Granada Ventures, part of ITV Worldwide.
