Media Week: Viacom has started the process of making more than 90 people working in Channel 5’s commercial team redundant following the decision to partner with Sky Media for its advertising sales. Viacom’s new five-year deal means Channel 5’s commercial airtime will be sold by Sky’s sales team starting in June 2015. The move means a dramatic end to one of the U.K.’s biggest commercial operations. Speculation about the future of Channel 5’s standalone sales operation has been mounting since Viacom bought the broadcaster from Northern & Shell in September 2014.
