According to Wikipedia, WSMB at 1350-AM (now WWWL-AM) WSMB was founded in 1925 as New Orleans' first professional radio station, a joint commercial venture by the local Saenger Theatre (the "S" in WSMB) and the Maison Blanche Department store (the "MB" in WSMB). Programming provided by the Saenger allowed Maison Blanche to sell radios (national networks would not provide programming for years to come). The studios were located on the thirteenth floor of the Maison Blanche Building on Canal Street, a few blocks from the theater for most of its history.
WSMB was a very successful news/talk outlet in the 1960s and 1970s primarily on the strength of morning drive personalities, Roy Roberts and Jeff Hugg, know as “Nut and Jeff” and midday political talk show host, Keith Rush. But by the 1980s its ratings had dropped. In 1988 it was auctioned off and by the 1990s it became the sister station to WWL-AM, first under the ownership of Sinclair Broadcast Group, and then Entercom.
WSMB's only notable format detours were between 1999 and 2001 when it flipped to all-sports-talk. Programming at that time included syndicated shows from ESPN Radio and an afternoon show hosted by local sports commentator Kaare Johnson. Other local personalities heard on the station included noted sports trainer Mackie Shilstone. A period where programming consisted of on-air psychologists, and most recently (until November 2006) carrying a progressive talk radio format as an affiliate of Air America Radio. The Food Show with Tom Fitzmorris remained on the air through all these format changes. It is the longest-running talk show of any kind in New Orleans, airing daily since July 18, 1988.
