WMDM aired an oldies music format prior to May 31, 2006.

On May 31, 2006, the station switched their callsign from WMDM-FM to WYRX and their format to Modern Rock under the branding "The Rocket".

On September 17, 2007, WYRX changed their call sign to WRKZ. The WRKZ calls had been attached to a Pittsburgh rock station until April 2007. The format has evolved into an active rock music format with the addition of artists like Aerosmith, Def Leppard, and Led Zeppelin to the playlist.

On January 22, 2008, WRKZ changed their call letters back to WYRX. Joe Sanchez was the Morning Show host and Program Director until February 2009.

On March 4, 2009, WYRX switched its call sign back to WMDM. On March 21, 2009, WMDM dropped its Active Rock format for adult contemporary and picked up the branding "Magic 97.7".

On April 21, 2009, WMDM brought back "The Rocket" branding and switched its format to Contemporary Hit Radio.

On November 30, 2009, WMDM switched formats to Easy Listening, branded as "Easy 97-7". The new format consists mainly of vocals (as opposed to the original instrumental-oriented Beautiful Music format).

On March 11, 2011, WMDM again changed their format to classic rock and again re-branded themselves as "97-7 The Rocket."

On the afternoon of April 18, 2017 WMDM changed their format to Active Rock, and continues to brand itself as "97-7 the Rocket". Disc Jockey "Blak Jak" announced the change on his 3 p.m. to 7 p.m. program.
