The BBC is planning a major online revamp in a bid to take on the might of streaming providers Netflix and iTunes.
According to reports in the Daily Mail, the public corporation intends to charge up to £5 for access to hit shows such as 'Doctor Who', 'Luther' and 'Sherlock'.
Viewers will be able to buy episodes or series months or years after they first air, enabling them to watch shows at their own convenience.
The news provider claims the broadcaster has already tested a BBC Store, and sought feedback on the on-demand service from focus groups.
In order for the new service to launch, approval would be required from the BBC's governing body.
Eventually, the broadcaster hopes to offer online access to almost every programme it makes.
The BBC iPlayer will still be available, offering on-demand access to shows after they have been shown on TV.
Under the existing proposals, BBC content would be freely available for 30 days after the broadcast date, rather than the current seven.
A spokesman for the BBC said: "We know people want to keep older programmes so we hope to launch BBC Store.
"This commercial online service will give people the opportunity to own a digital copy – just like they can on DVD – to watch and keep."
However, Rob Wilson MP warned the BBC against charging licence-fee payers for the content it produces.
He said moves towards online content provision raise "significant questions" as to whether the current BBC funding model works in a digital age.
