WMGX airs an Adult Top 40 radio format and is owned by Saga Communications.

Core artists included James Taylor, Carole King, Cat Stevens and Carly Simon.

From the mid-to-late-1980s and through the 1990s, WMGX had a unique format, blending classic, soft, and progressive rock with adult contemporary music.

WMGX eventually dropped the "80s, 90s and Now" slogan and changed it to "Today's Best Mix" to reflect the playlist from the current and recent Top 40 charts, minus any songs deemed too hard-edged or rap-oriented.

On Sunday mornings, WMGX airs the nationally syndicated show American Top 40 with Ryan Seacrest.
