For the history of the 1250 frequency prior to WHNZ, see WDAE.
Early years
WHNZ is the successor of two radio stations, co-owned WDAE, one of Florida's oldest radio stations, going on the air May 15, 1922; 102 years ago (May 15, 1922). WDAE spent most of its history at AM 1250 before moving to AM 620. The station was co-owned with the Tampa Times daily newspaper.[6]
WHNZ also has history on AM 570 in Pinellas Park. That was the original frequency that carried the WHNZ call sign and aired some of the same business and financial shows that are heard on today's WHNZ.
Paxson Communications
On October 24, 1991, what was then WPLP was bought by Paxson Communications, the company founded by multi-millionaire Bud Paxson after he had sold the Home Shopping Network.[7] Unlike today's WHNZ, Paxson put a full-time business and financial station on AM 570, changing the call sign to WHNZ. Those call letters refer to "Wins Radio", meaning that it will help you win in the business world.
In 1998, Clear Channel Communications, the previous name of iHeartMedia, bought AM 570. It also bought AM 620 from Cox Communications, after Cox had moved what was WSUN and its adult standards format to co-owned AM 910 in nearby Plant City, Florida, in anticipation of a sale. Once Clear Channel owned all three frequencies, 570, 620 and 1250, it was able to execute a three-way frequency swap.
Changes in frequencies
On New Year's Day 2000, WDAE's sports format and call sign moved to AM 620. WHNZ's business format and call sign moved to AM 1250. Clear Channel put a news/talk format on AM 570, giving it the call signWTBN, which stood for "Tampa Bay News". The following year, Salem Communications took over AM 570, installing a Christian radio format, heard currently on WTBN.[8]
WHNZ was the flagship station of the Tampa Bay Raysbaseball team from 2005 to 2008, now heard on WDAE. As of 2011[update], WHNZ airs select sporting events moved from WDAE or WFLA due to schedule conflicts. Beginning on May 19, 2018, WHNZ will be the radio home of the Tampa Bay Rowdies.[9]
Weekday mornings began with This Morning, America's First News with Gordon Deal. In afternoon drive time, WHNZ carried The Todd Schnitt Show. (Schnitt for many years was a host on co-owned WFLA. His syndicated show aired in Tampa Bay on WHNZ live at 3 p.m. and was replayed on WFLA at 6 p.m.). At night, WHNZ carried Fox Sports Radio. Brokered programs on money, business and health were heard in middays, evenings and weekends. CBS Radio News began most daytime hours.
Spanish Talk and English Talk
On July 26, 2021, WHNZ changed its format to Spanish-language news/talk, branded as "Acción 1250".[10] It had been simulcast with WRSO in the Orlando area.
On January 11, 2024, WHNZ switched back from Spanish news/talk to a mix of English-language talk and business news, branded as "Impact Radio".[11] The station began carrying a mix of financial news and information from Bloomberg Radio along with syndicated talk shows not airing on co-owned talk station WFLA 970.
