Introduction

At&t was found on October 5, 1983 and officially transferred the ownership from Southwestern Bell Company on January 1,1984. However, it was operating under subsidiaries of Southwestern Bell Publications, Inc., a directory publisher; Southwestern Bell Mobile Systems, Inc., in the business of mobile telephone service; and Southwestern Bell Telecommunications, Inc., focusing on marketing phone equipment to business customers. In 1987, SBC bought Metromedia Inc.'s cellular and paging business. This in turn boosted the company to third largest cellular-communications company in the United States; behind McCaw Cellular and Pacific Telesis.

At&t strategy still remain the same for today by acquisition of the other telecommunication company to expand their businesses, services and customers. The most recent acquisition is on March 20, 2011 which At&t acquired T-Mobile, this would result At&t monopolizing 43% of U.S mobile services. They slogan "Rethink Possible"  really making the consumer to re-think the possibility of one America, one company strategy. In business stand point it is a very good idea but consumers' stand point is a dangerous and risky if that happened, simply because if there is only one company in the U.S, At&t could charge any rates and any plans, and policies as they wish. Which also means At&t would control the industry of telecommunication and eventually will conquer the whole world telecommunication industry as well.
