Verizon Wireless (NYSE: VZ), AT&T (NYSE: T), T-Mobile US (NYSE:TMUS) and Sprint's (NYSE: S) emergence as the top four wireless operators came through an aggressive campaign of consolidation of a number of regional providers, including Alltel, Leap Wireless, MetroPCS and others.
All of this consolidation has left the wireless industry with only two regional operators that have over 1 million subscribers (U.S. Cellular with 4.8 million customers and C Spire Wireless with around 1 million customers).
FierceWireless, in partnership with Quexor Group, looks at acquisition patterns of the four major wireless carriers during the past 10 years. Take a look at the report here.
