Dallas Cowboys sell stadium naming rights: it's now AT&T Stadium ARLINGTON, Texas, July 25 (UPI) -- The Dallas Cowboys said Thursday their stadium will be called AT&T Stadium, after agreement on naming rights was reached with the telecommunications company. Cowboys owner Jerry Jones sought a deal in the area of $25 million per year to attach a corporate name to the Arlington, Texas, stadium, but received an offer from AT&T for less than $20 million per year, Sports Illustrated reported Thursday. The stadium, which cost $1.1 billion to construct, opened in 2009, a year with an economic climate not conducive to striking a significant deal for naming rights, the Dallas Morning News said. The arrangement to rename the building originally known as Cowboys Stadium is expected to go into effect immediately, the newspaper said.
