The Times and Sunday Times of London will begin charging for online subscriptions in June, a move that is meant to boost paper subscription sales. "'Adios. Give me a call when you're free again,' posted Jeannine Steward on Times Online yesterday, shortly after Rupert Murdoch's News International announced that from June it would be charging £2 a week for access to the websites of The Times and The Sunday Times. The introduction of this internet paywall, first announced by Mr Murdoch last August as he suffered the humiliation of posting a huge annual loss for his global media empire, is a step into the unknown for the most famous newspaper mogul of them all. Since then, his henchmen have been working overtime in an effort to solve a conundrum that has been vexing traditional media companies for several years: how do you challenge the apparently ingrained concept that online news comes for free?"
