Previously owned and operated by the City of Springfield and various management groups until 1997, the city transferred ownership of the facility to the Massachusetts Legislature. Shortly after, ownership was given to the Massachusetts Convention Center Authority (MCCA) who in turn began working on plans to renovate and expand the facility. The two-year project, which began in 2003, included renovations to the 8,000-seat arena and the addition of a convention center. Its unique design allows for 3 to 4 concurrent events or one large event. MGM Springfield began operating the venue on behalf of the MCCA in July 2017 in advance of its casino/hotel/retail development opening the next year. In 2005, the venue was renamed when Massachusetts Mutual Life Insurance Company entered into a 15-year naming rights agreement for the arena and convention center. The name change took place on September 29, 2005. The venue is home to the Springfield Thunderbirds of the American Hockey League and American International Yellow Jackets who compete in NCAA Men's Division I Ice Hockey.
