Media Brief

I'm the BBC's media correspondent and this is my brief selection of what's going on.

As Tate Britain holds its summer party, its 20-year sponsorship deal with BP has been attacked by more than 160 artists and writers, in a letter to the Guardian. They will picket the party saying BP's cultural sponsorship masks its damage to the environment.

The issue is debated on Radio 4's Today programme by Greenpeace's Charlie Kronik and the former head of the Arts Council of England, Sir Christopher Frayling.

The BBC reports that the government wants to tighten the rules on council-run free newspapers, says the BBC. Local Government Secretary Eric Pickles said independent local papers should not face competition from "propaganda on the rates".

Brand Republic reports that WPP boss Sir Martin Sorrell has likened social media to letter-writing at the Cannes Advertising Festival. He said it could be 'polluted' by attempts to monetise it.

The audience for the final episode of the new Doctor Who series was hit by the sunshine, according to the Sun, but the Mirror's Jim Shelley says it's been a triumph. Gavin Fuller in the Telegraph describes it as "interesting and enjoyable" but "not quite the spectacular conclusion you might hope for".

There are photos from the new Harry Potter film trailer, which is released tomorrow (though the film doesn't come out till November). Meanwhile, the third episode of the Twilight saga is out shortly. The Mirror compares the two.

England's World Cup exit dominates the newspapers, reports the BBC newspaper review.
