London agency The Brooklyn Brothers has won the creative account for the Tate galleries.
It will work on the advertising and communications strategy for the four Tate galleries which include Tate Britain and Tate Modern.
"I’m looking forward to working with them on our future campaigns with an aim to broaden the range of audiences who experience art," said Tate Media and Audiences director Marc Sands.
Ali Alvarez, creative partner at The Brooklyn Brothers, added: "There are some pretty amazing thinkers at Tate, so for them to choose us as their partners for their next chapter is an absolute honour. We can't wait to get started."
