ORCHARD PARK, N.Y. (AP) —The Buffalo Bills' home has a new name: Highmark Stadium. The newly rebranded health insurer, Highmark BlueCross, BlueShield of Western New York, has purchased the naming rights for what was simply known as Bills Stadium last season. The move comes after Pittsburgh-based Highmark Inc. completed an affiliation agreement with the Buffalo-based HealthNow New York. The stadium's naming rights were available after Buffalo-based New Era Cap Company backed out of its agreement in July.
