Two major national media deals under consideration would each have a significant impact on the Denver TV market. As previously reported, Sinclair Broadcast Group is hoping to buy Tribune Media Co. in a $3.9 billion deal that would create a national broadcasting monolith. Denver has two Tribune-owned stations: KDVR and KWGN. At the same time, Rupert Murdoch’s 21st Century Fox is close to buying as many as 10 stations from Sinclair, probably including Denver’s KDVR, which might be spun off by Sinclair to win regulatory approval.
