On December 5, 1947, WHOO first signed on the air. It was the ABC Radio Network affiliate for Orlando and was co-owned with the Sentinel Star newspaper. The studios were in the Fort Catelin Hotel. An advertisement in the 1948 Broadcasting Yearbook said that WHOO celebrated its debut broadcast with 5,000 guests, a New Yorkdance band and a full-time "girl singer." It boasted that it had Orlando's first city room to gather local and Florida news stories and the largest sports staff. A short time later, it added an FM station, 96.5 WHOO-FM. In the late 1950s, as network programming moved from radio to television, WHOO shifted to a Top 40music format and was a top-rated station in the market until slipping behind upstart AM 950WLOF "Channel 95" in the mid-1960s. WHOO then switched to country music in 1968 and continued with this format until 1987, when the station switched its call sign to WMMA "Magic 99." airing a satellite-fed soft adult contemporary format from the Satellite Music Network. A short time later, it changed to oldies.
Standards, country and rock
A succession of formats followed over the next several years: the station was briefly WHTQ in 1988, simulcasting the album rock format of WHTQ-FM. It returned to the WHOO call sign with an adult standards format known as "The Music of Your Life." Within a year, it changed to classic country in 1989 and then returned to simulcasting WHTQ-FM's rock music from 1990 to 1993. In 1993, WHOO returned to adult standards, this time using the syndicated "Stardust" format from ABC Radio.
In 2001, WHOO was acquired by the Walt Disney Corporation for $5 million. With Orlando the home of Disney World, it was logical the company would flip WHOO to children's radio. The station became WDYZ as a Radio Disney owned and operated station. The DYZ stood for "Disney." The standards format and WHOO call letters were shifted onto AM 1080 in Kissimmee. On August 13, 2014, Disney put WDYZ and 22 other Radio Disney stations up for sale, in order to focus on digital distribution of the Radio Disney network. On December 15, the Radio Disney Group filed to sell WDYZ to the Pennsylvania Media Associates, Inc. Pennsylvania Media is a subsidiary of the Salem Media Group. The FCC granted the sale on February 10, 2015.
Salem ownership
On March 10, 2015, Salem Media CEO Ed Atsinger revealed that WDYZ would be the eighth company-owned station to carry Salem's "Radio Luz" SpanishChristian format. On March 18, 2015, WDYZ dropped Radio Disney programming and went silent. The sale was consummated on March 27, 2015. On April 13, 2015, WDYZ returned to the air with a Spanish Christian format, branded as "La Nueva 990." On August 5, 2019, WDYZ flipped from Spanish Christian programming to English-language Christian talk and teaching, branded as "The Word." It was part of a Salem Media shuffle of its Orlando stations. AM 660WORL, the home of Salem's conservative talk format, was sold. Salem shifted WORL's programming and call sign to AM 950. In turn, the WTLN call letters and Christian talk and teaching format moved up the dial to AM 990.
