Dish Network is in discussions with T-Mobile over a potential merger, a report claims. According to sources of the Wall Street Journal, the two companies are said to be at the "formative stage" of the merger talks, with the potential purchase price still yet to be decided upon, but the eventual structure of the combined company has already apparently been sorted out, with Dish CEO Charlie Ergen becoming chairman and T-Mobile CEO and President John Legere becoming the CEO.
