Johnson, 47, died suddenly on Wednesday. He started his career at Grampian TV in 1988, moving to British Satellite Broadcasting, subsequently Sky, before joining Flextech’s sales house in 1996.
He was part of the senior negotiating team at IDS and also ran new business and the team that launched the Setanta channels portfolio.
James Wildman, managing director, said: "Jonners was the very best of men, one of the 'good guys' - funny, generous, popular and loving with enormous 'joie de vive'; an exceptional father, husband, colleague and friend. We will miss him so much and the media industry has tragically lost one of its stars."
