AT&T INC. Annual Report, Year Ended Dec 31, 2015

AT&T Inc.'s 2015 10-K report highlights a pivotal year of strategic transformation, marked by significant acquisitions and a renewed focus on integrating its diverse communications and entertainment offerings. The company completed the acquisition of DIRECTV, significantly expanding its digital entertainment reach across the U.S. and Latin America, and also acquired wireless operations in Mexico to establish a cross-border North American network. These moves underscore AT&T's ambition to become a leading provider of integrated communication and digital entertainment services. The report details a restructured business model with four key segments: Business Solutions, Entertainment Group, Consumer Mobility, and International. A key strategic shift is the move away from traditional device subsidies towards installment payment plans (AT&T Next) and the "bring your own device" model, signaling a focus on service revenue over hardware sales. The company also continues to invest heavily in network modernization, particularly in IP-based technologies and expanding wireless capacity to meet growing data demands, while acknowledging spectrum constraints as a potential challenge. AT&T is actively managing the sunsetting of its 2G networks to reallocate spectrum for more advanced services.
