Such Hearst titles as Cosmopolitan, Marie Claire and Harper’s Bazaar are collaborating on the Hello Style channel on YouTube, beginning last weekend. YouTube is spending $100 million to help media companies launch the programmes, in the belief that the higher-quality content will bring in more advertisers. Publishers hope video and other platforms will make up for slower print advertising growth. Next up on May 1 is the Car and Driver TV channel, from Hearst’s motoring magazines.
