The Buffalo Bills Radio Network is flagshipped at WGR, AM 550 in Buffalo, owned by Entercom. John Murphy is the team's current play-by-play announcer; he was a color commentator alongside, and eventually succeeded, longtime voice Van Miller after Miller's retirement at the end of the 2003 NFL season. Mark Kelso serves as the color analyst. The Bills radio network has approximately seventeen affiliates in upstate New York and one affiliate, CJCL 590AM (The Fan) in Toronto. As of early 2012, it is composed mostly of WGR, Entercom's sister stations WCMF (96.5 FM) and WROC-AM 950 in Rochester, and a fleet of independent AM and FM stations across upstate New York from Jamestown east to Albany. Previous flagship Citadel Broadcasting was purchased by Cumulus Media, who in turn ceased carrying Bills games at the end of the 2011 season, leaving the network without affiliates in Syracuse, Binghamton, and Erie. (The Syracuse affiliations were later picked up by Galaxy Communications.)
