WFXZ-CD, virtual channel 24 (UHF digital channel 24), is the MundoMax-affiliated television station located in Boston, Massachusetts, United States. The station is owned by Prime Time Partners. WFXZ-CD maintains studio facilities located in Woburn, and its transmitter is located in the Newton Upper Falls district of Newton. The station is available on Comcast Xfinity digital channels 300, 721 and 981, and Verizon FiOS channel 20.
The station's construction permit was originally granted on November 30, 1989 as W29BA, operating on channel 29, which would be licensed to nearby Lawrence. However, by the time finally it signed on the air with a home shopping service in early 2000, it had moved to channel 24, was licensed to Boston and adopted the W24CM call sign.
A few months later, channel 24 changed its call letters to WVXN-LP. In 2001, the station was upgraded to Class A status and dropped home shopping programming in favor of affiliating with MTV2. The station changed its callsign to WFXZ-CA in 2003. In July 2006, the station became the Boston affiliate of the Azteca América network (later renamed simply as "Azteca").
