Wagg is a surname. Notable people with the surname include:
WAGG (610 AM) is a radio station licensed to Birmingham, Alabama. It broadcasts at a daytime power 5,000 watts, and at nighttime, it broadcasts at 1,000 watts from a transmitter in the city's westside. WAGG is a gospel music station that targets Birmingham's African-American population. It is owned by Summit Media, which also owns six other stations in the market, and all share studios in the Cahaba neighborhood in far southeast Birmingham. The station was assigned the WAGG call letters by the Federal Communications Commission on January 15, 1999.
Some generations ago, the 610 AM frequency was home to Birmingham’s second oldest radio station. That station began in 1926 as WKBC, broadcasting at 1310 AM. The original owner of the station was a local furniture company. In 1932, the station was sold to The Birmingham News, and the callsign was changed to WSGN. That callsign stood for "South’s Greatest Newspaper," an obvious tribute to The Chicago Tribune’s WGN, whose callsign stands for "World’s Greatest Newspaper."
