From WWE.com:
WWE Hall of Famer Jim Ross announced that he is retiring from WWE today, after 20 years of service, to focus on his personal business endeavors.
Jim has had a long and storied career at WWE, both on the corporate staff as well as his television persona, calling some of the most memorable matches in WWE history as the voice of Monday Night Raw and SmackDown for more than two decades. He made his debut with WWE at WrestleMania IX in 1993 and was inducted into the WWE Hall of Fame in 2007 by his long-time friend “Stone Cold” Steve Austin.
Jim has made many contributions to WWE and the sports-entertainment industry, and we thank him for his many years of service and wish him well.
