The year 2003 in radio involved some significant events.

Events

October 10 – Facing an investigation surrounding allegations of illegal drug use, American right-wing radio host Rush Limbaugh publicly admits that he is addicted to prescription pain killers, and will seek treatment.

March 3 – Skratch 'N Sniff debuts on San Diego area alternative rock station XETRA-FM (91.1 FM, "91X").
March 31 – "NBC News Radio," an hourly service of one-minute news updates anchored by NBC News and MSNBC personnel (but written by Westwood One staffers) is launched. Westwood One still maintains production of the unrelated five-minute long "NBC Radio News"-branded newscasts in morning drive (which had been produced and anchored by CBS Radio personnel since 1998) for one more year; they were one of a few remaining connections to the original NBC Radio Network.
April – KJOC in Davenport, Iowa dumps its all-sports format and switches to talk, hoping to compete with the market's WOC. Some sports programming – mainly, the Chicago Cubs and Iowa State University athletics – are held over, and (except for a few brief interim periods with ISU sports) remain to this day.
October 12 – Billboard unveils the Hot Dance Airplay chart. "Just The Way You Are" by Milky is the first number one single on the published chart.

All stations have since left the Dance format and panel.
