Singh, who takes up his role in April, will oversee all revenue generation and its key commercial relationships, as well as customer-facing activities.
He replaces Sanjay Patel, who will focus solely on his role as managing director of new competition for the board.
Singh has played a leading role in BT TV and BT Sport’s growth over the past five years, leading the team responsible for the broadcaster’s cross-supply content deal with Sky and commercial distribution of BT Sport to other platforms. The move is said to have doubled its advertising revenues and developed a host of successful digital initiatives.
Before joining BT in 2014, he also held senior management positions with the consumer marketing agency, Nectar, and the BBC’s Commercial Agency.
BT has seen a string of executives depart in recent months, including chief executive Gavin Patterson who left the company last June.
ECB CEO Tom Harrison said: “Tony brings a wealth of experience in dealing in complex commercial environments and has a proven track-record of delivering success across sports and media organisations. His experience and industry knowledge in a fast-changing media landscape will be a tremendous asset to our leadership team.
Singh said: “Cricket has been a lifelong passion of mine. I was immensely proud to play a part in helping the BT Sport team bring a new audience to the game following our major broadcast rights deal with Cricket Australia including last winter’s Ashes series.
