Anyone that calls the UK home will know that Tesco is a retail behemoth and, like many other supermarkets, has turned into a one-stop shop for everything from a pint of milk to the latest video game releases. It's grown into much more than a store, however, running an MVNO (although it sometimes gets confused about hardware) and the subscription-based video streaming service Blinkbox. Last year, Tesco let its wider digital ambitions be known, acquiring both a music streaming service and an e-book publisher. We've now been told these companies are the primordial soup from which its new online content emporiums will spawn later this year, known as Blinkboxmusic and Blinkboxbooks, respectively. And who'll be responsible for these new ventures? Well, they're somebodies -- Gavin Sathianathan, who was previously Head of Retail (EMEA) at Facebook, will head up the e-book offering, while Mark Bennett, formerly Head of Digital & Cross Channel at rival super-supermarket Sainsbury's, will run the musical endeavor. Tesco also announced that former Blinkbox exec Scott Deutrom is taking the reins of Clubcard TV, a new ad-supported video streaming service currently being tested. So, what's next for Tesco, apart from world domination? If industry trends are anything to go by, a mobile OS, most likely.
