WWIZ (103.9FM) is acommercialradio stationlicensed toWest Middlesex, Pennsylvania, serving theMahoning Valley includingYoungstown, Ohio. It airs anadult contemporaryformat, using the branding "Z 104" and carring theWestwood One "Hits & Favorites" network. It is one of seven radio stations in the Youngstownradio market owned byCumulus Media with studios in "The Radio Center" in Youngstown.
WWIZ operates with aneffective radiated power (ERP) of 6,000 watts, making it aClass A station.[2] Thetransmitter is on Greenfield Road inHermitage, Pennsylvania.[3]
WWIZ firstsigned on the air in October 1972, playingalbum rock. The station carried anactive rock format for several decades, branded as "Rock 104".
On March 31, 2017, WWIZ dropped its active rock format and beganstunting. It played a continuous loop ofThe Moody Blues' “Nights in White Satin” andThe Royal Guardsmen's “Snoopy vs. the Red Baron”, with just astation identification between the songs. The following day at noon, the station flipped tooldies as "Z104" usingWestwood One's "Good Time Oldies" satellite feed.[4]

On April 17, 2025, WWIZ changed its format from oldies toadult contemporary music (AC), still under the "Z104" branding. It switched to the Westwood OneHits & Favorites network. This left the Youngstown market without a full-time classic hits or oldies station. WWIZ had been effectively forced to change formats because of Westwood One's plan to shut down the "Good Time Oldies" network that month.[5]

Between 2019 and 2022, WWIZ temporarily displaced its oldies format in favor ofChristmas music during theholiday season and became known as "Christmas 104".
The change first occurred on October 25, 2019, when WWIZ dropped its oldies format and began carrying Christmas music. It was the first U.S. station that year to flip to Christmas music for the holiday season and initially appeared to be astunt.[6] However, on January 1, 2020, WWIZ ended the Christmas music and returned to its previous oldies format, branded as "Z104".[7]
On September 25, 2020, at 12:25 p.m., WWIZ again flipped to Christmas music. It made this unusually early change due to the stress of theCOVID-19 pandemic. It is theearliest known flip to Christmas music for an FCC-licensed station; the earliest stations,including stunting stations, typically flip to the format in mid-October.[8]
On October 1, 2021, at 12:25 p.m., WWIZ again flipped to Christmas music, branded as "Christmas 104". This year, it was not the first station to change, asWXMS made the flip a few hours earlier.[9]
In 2022, WWIZ opted not to repeat the excessively early flips of the previous years, and by October 31 of that year, the station was still playing its regular format. On November 1, 2022, at 12:25 p.m., WWIZ finally switched to its Christmas music format, becoming Christmas 104, and continued the format throughNew Year's Day.
In 2023 and 2024, WWIZ decided not to run an all-Christmas music format. Starting in late November, the station mixed in a few Christmas songs into its regular oldies format and retained the "Z 104" branding, as opposed to switching to "Christmas 104".
On November 1, 2025, WWIZ opted to bring back the all-Christmas format after a two-year break of not doing so. The station re-adopted the "Christmas 104" branding used from 2019-2022.
