Not surprisingly, we can now count DirecTV CEO Mike White among those who oppose Comcast’s proposed Time Warner Cable acquisition. During the pay TV provider’s earnings call on Thursday afternoon, White was asked to share his feelings on the merger that would see two of the country’s largest TV and Internet providers merge into a single giant. According to an account from The Wall Street Journal, White said that the deal would create “unprecedented media concentration in one company,” and the combined entity would have an “effective monopoly” in two-thirds of the United States. Dish chairman Charlie Ergen had previously said that there would be some benefits to the Comcast-TWC merger, but he expressed doubt that regulators would ever approve the deal.
