WANN (1190 AM) was a radio station based out of Annapolis, Maryland that primarily served the area's growing African American community. Morris Blum founded it in 1946, and it broadcast to the entire mid-Atlantic region. The station was home to disc jockey Charles "Hoppy" Adams starting in the early 1950s. Adams hosted weekly events at a local African American only beach, Carr's Beach, which were popular with the area's youth population.

WANN continued to program gospel, rhythm and blues, and public affairs features until 1992 when the station changed to a mainstream country format with the catchphrase “Bay Country 1190.” Around 1998, the station changed ownership and became WBIS, broadcasting a News Talk Information format.
