Metrocall

Metrocall, Inc., originally incorporated as Advanced Communications Inc. in 1965, grew from a regional Mid-Atlantic paging company into the second-largest paging and wireless messaging provider in the United States, serving more than six million subscribers by 2000. Headquartered in Alexandria, Virginia, Metrocall expanded through an aggressive acquisition strategy — including ProNet, AT&T Wireless's Advanced Messaging Division, and Page America — before merging with rival Arch Wireless's successor WebLink Wireless in 2004 to form a combined paging and wireless-messaging company based in Alexandria.
