Crown Castle Inc.
A company that owns and rents out tens of thousands of cell towers across the United States, letting wireless carriers like AT&T, Verizon, and T-Mobile share the same structures instead of each building their own. Crown Castle began in 1994 as Castle Tower Corporation in Houston and took its name from a 1997 merger with Crown Communications. The name playfully combines two of the companies' names — the Crown family's firm and the "castle" of Castle Tower.
