Sounds kind of like a low-budget horror flick, doesn’t it? Many have pointed out that with AT&T acquiring BellSouth, the days of the large telco are really returning. But today Om Malik is citing a study by TNS Telecom that reveals just how large we’re talking here. According to the study, once the acquisition goes through AT&T will control 22% of all consumer dollars and 34% of all business dollars spent on telecom services. And if you add Verizon and Comcast to the mix, we’re looking at 3 companies controlling 49% of the total consumer market. Hold on to your seats, this could be a spooky ride.
