Media Talk: Edinburgh TV festival 2010

This time last year, BSkyB boss James Murdoch launched a tirade against the "chilling" effect of the BBC. This year, it fell to BBC director general Mark Thompson to launch the fightback . His MacTaggart lecture was billed as the speech of his life – but did it deliver? Matt Wells is joined in Edinburgh by Steve Hewlett , Maggie Brown and Jane Martinson to hear their verdict. Also in Edinburgh, we hear from the new Channel 5 programme chief Jeff Ford – who was installed in the job only two weeks ago after a boardroom cull – on his vision for the channel and his relationship with new owner Richard Desmond. Plus, acting Channel 4 chief creative officer Julian Bellamy tells the festival about the effect of axing the broadcaster's biggest show, Big Brother. We've also got a view on the state of British TV drama from the chief executive of Left Bank Pictures, Andy Harries, the man behind Wallander. And if there wasn't enough campery, we've got an interview with Louis Spence of Sky One's Pineapple Dance Studios, who gives us his view on whether he perpetuates a stereotypical image of gay men. Warning: may contain evidence of regrettable nights on the lash.
