It follows from the company’s strategy that the legacy wireline business remains a key component of its business. While wireline voice has experienced significant revenue decline with the advent of wireless technology, AT&T has kept its 22-state wireline business intact and continues to provide a full spectrum of voice, data, and video services. Importantly, AT&T has not slowed innovation and adoption of new technologies for its wireline business. The company has invested heavily in expanding its fiber optics network across its 22-state region to offer high-speed Internet access and streaming video services to its customers.
