에이티앤티(AT&T) - Best Coverage

In 1994, AT&T purchased the largest cellular carrier, McCaw Communications, for $11.5 billion and kick-started its cellular division with 2 million subscribers.
In 1995, AT&T purchased long-distance provider Alaska Communications System (Alascom). FCC approval required the company be run as an AT&T subsidiary rather than a more likely absorption into AT&T Communications, giving the company the AT&T Alascom name.
In 1997, AT&T hired former IBM executive C Michael Armstrong as its chief executive officer. Armstrong's vision was to change AT&T from a long-distance carrier into a global "telecommunications supermarket", eyeing Internet services for the booming dot-com industry.
