ITV has taken a stake in Channel Mum, a YouTube network looking to make stars of British “mummy vloggers.” The broadcaster has taken a minority stake in the fledgling venture which was launched by Siobhan Freegard, the co-founder of parenting Web site Netmums, in January. Channel Mum, which runs with the strapline “the honest face of parenting” has 10 vloggers signed up, has signed deals with companies including Pampers, although it has a YouTube subscriber base of just 2,140.
