American Personal Communications (APC) to create a digital wireless network. In November 1995, the company began to offer wireless service under the Sprint Spectrum brand in the Baltimore-Washington metropolitan area. This was the first commercial Personal Communications Service (PCS) network in the United States. Although the Sprint PCS service was CDMA, the original Washington-area network used GSM. Eventually, Sprint launched its new nationwide CDMA network, then in 1999 sold the decommissioned GSM infrastructure to Omnipoint which re-launched in May 2000. Omnipoint was later acquired by VoiceStream Wireless, which eventually became part of T-Mobile US. Sprint and T-Mobile US merged in 2020. Partnerships and more consolidation In September 1996, Sprint announced a deal with RadioShack, and in 1997, Sprint stores opened at RadioShack to offer communications services and products across the United States. On October 5, 1999, Sprint and MCI WorldCom announced a $129 billion merger agreement between the two companies. The deal would have been the largest corporate merger in history at the time. However, due to pressure from the United States Department of Justice and the European Union on concerns of it creating a monopoly, the deal did not go through. In 1999, Sprint began recombining its local telecom, long-distance, wireline, and wireless business units into a new company, in an initiative known internally as "One Sprint". In April 2004, the separately traded wireless tracking stock PCS was absorbed into the New York Stock Exchange FON ticker symbol, Sprint's former ticker symbol (FON stood for "Fiber Optic Network", but was also a homophone of the word "phone"). This was challenged in many lawsuits by Sprint PCS shareholders who felt their stock was devalued because it was trading at the ratio of 1 share of PCS stock for 1/2 share of FON stock. The PCS shareholders claimed a loss of 1.3 billion to 3.4 billion dollars. Merger of Sprint Corporation and Nextel Communications On December 15, 2004, Sprint Corporation and Nextel Communications announced they would merge to form Sprint Nextel Corporation. The merger was transacted as a purchase of Nextel Communications by Sprint Corporation for tax reasons; Sprint purchased 50.1 percent of Nextel. At the time of the merger announcement, Sprint and Nextel were the third and fifth leading providers in the U.S. mobile phone industry, respectively. Sprint shareholders approved the merger on July 13, 2005. The merger deal was approved by the U.S. Federal Communications Commission (FCC) and U.S.
