The UK is moving ahead with a plan to regulate big tech, responding to competition concerns over a ‘winner takes all’ dynamic in digital markets. It will set up a new Digital Market Unit (DMU) to oversee a “pro-competition” regime for Internet platforms — including those funded by online advertising, such as Facebook and Google — the Department of Digital, Culture, Media and Sport (DCMS) announced today. It’s moving at a clip — with the new Unit slated to begin work in April.
