The station
signed on as WAMR on February 1, 1960. It was owned by Venice Nokomis Broadcasting, Inc. and was a
daytimer station, with a power of 500 watts, and required to
sign off at sunset to avoid interfering with other stations on
AM 1320. It aired a
middle of the road (MOR) music format. In the 1980s, the daytime power was increased to 5,000 watts and the station was given nighttime authorization with 1,000 watts. In 1988, the station was acquired by Asterisk Radio, Inc., which kept the MOR format in the daytime but added talk programming from
NBC Talknet at night. In the 1990s, the music was decreased and talk programming took over the daily schedule. In 1999,
Citicasters acquired the station. Citicasters later merged into
Clear Channel Communications, which today is iHeartMedia, Inc. After top-rated
WDUV (103.5 FM), an
easy listening station, switched to a
soft adult contemporary format and moved to a transmitter north of Tampa, Clear Channel decided to go after its displaced listeners in the Sarasota area. WAMR became WDDV, a
call sign similar to the departed FM station. WDDV's format changed to
adult standards. On March 17, 2016, WDDV flipped from adult standards to
talk and business news. On weekdays, WDDV
simulcast the morning
drive time show, "AM
Tampa Bay", from
WFLA in Tampa. The rest of the schedule consisted of
syndicated talk shows and business news from
Bloomberg Radio. Some hours were paid
brokered programming. On May 5, 2020, iHeartMedia flipped WDDV from news/talk to
oldies, branded as "Oldies 1320", using iHeartMedia's Real Oldies network. The call sign was changed to WDIZ on June 29, 2020. ==References==
