Sir David Jason has said he thinks the BBC values show ratings more than providing entertainment nowadays.
The Only Fools And Horses star told the Daily Mirror that he felt the broadcaster wasn't interested in nurturing series any more and instead was going for quick ratings wins.
Sir David, whose BBC sitcom The Royal Bodyguard was cancelled after one series, agreed that shows were given more time to find their feet in the past.
He said: "I think that's very true. We live in such a different, competitive world. But if the BBC nursed shows occasionally like in the past, they would occasionally win. I think they've got slightly obsessed with competing and not thinking about entertaining, which is their main priority.
"Maybe viewers will go down a bit [if the BBC pursues new programmes], but they will bounce up in my estimation because what they're forgetting about is that people still talk, or they'll tweet or whatever.
"They will still go 'did you see that programme last night?' And you'll either go 'no I was watching the news' or something. But eventually you'll go 'you missed a great show last night'."
Sir David added: "The BBC is supposed to be the bastion of good taste, good humour, information. It seems to be losing a bit of that attitude."
Open All Hours is back for a Christmas special this year and Sir David said he would consider reviving the 70s sitcom: "Yes, if it works to the need for the BBC to think the audience would love it I'd certainly do that."
