Sainsbury’s has announced a multi-year deal with Channel 4 to become the exclusive broadcast sponsor of the Great British Bake Off franchise. The partnership will be the biggest in the shows history, which Sainsbury’s credits to the ‘mass appeal’ of the show. The ‘Taste The Difference’ range will be the broadcast sponsor for the 13th series of Bake Off, as well as all spin-off shows, including Bake Off: An Extra Slice, Bake Off: The Professionals, Junior Bake Off and any specials.
