Most people are familiar with the top three wireless carriers in the United States: AT&T, Verizon and Sprint. But not everyone can name the remaining seven in the country’s “top ten”. This handy chart shows who they are and how they ranked in the first quarter of 2008. It also provides stats on their subscriber base, their recent subscriber additions, their revenue and some other details of the business. The two leading companies drew in about $11 billion in revenue and one and a half million subscribers each. Of course, all this will change soon if planned acquisitions (like Verizon buying Alltel and Rural Cellular) are allowed to go through.
