The move came a few weeks after AT&T withdrew its application from the Department of Justice (DoJ) following heavy regulatory attacks. The DoJ in August and the Federal Communications Commission in November blocked the proposed takeover citing concerns relating to unfair competition, layoffs, higher prices, lower innovation and investments in the industry. According to the regulators, the combination would have created a duopoly market for the U.S. wireless industry, giving AT&T and Verizon Communications Inc. ( VZ ) almost 80% control over the U.S. wireless post-paid market.
