In February 2006, WLIT began broadcasting in High Definition (HD). WLIT's HD-2 format (WLIT-HD2) is a disco/1970s format, but in December 2007 with the Holiday Lite going back to the original format, (WLIT-HD2) extended the Christmas music til New Years Day & then going back to the disco format on January 2.
From November through Christmas day, WLIT changes its branding to The Holiday Lite and format to Christmas music resuming its regular branding and format on December 26th.
WWEL was "Well" in the 1960s to describe the easy listening format that was broadcast on 93.9 FM. It was also that way long before. WWEL changed call letters to WLAK in the early 1970s. At that time Viacom bought WLAK. WLAK continued to play mostly instrumental easy listening but increased vocals to about four an hour. In 1983 WLAK switched to Soft AC playing 99% vocal songs and virtually no instrumentals. Core artists were Neil Diamond, Barbra Streisand and others. WLAK was very successful in the format, actually one of the first in the nation preceding its sister station WLTW in New York. WLAK changed call letters in late 1989 to WLIT, as Lite FM.
WLIT 93.9 FM has continued to broadcast in the Chicago area since then. In the mid 1990s WLIT evolved out of Soft AC and into a straight AC format. Viacom sold their radio stations to Chancellor in 1997 making WLIT a Chancellor station. Chancellor restructured and became known as AMFM inc in 1999. In 2000 AMFM inc merged with Clear Channel Communications making WLIT a Clear Channel station.
In November 2007, WLIT dropped Delilah and brought in John Symons and his "Love Notes" show for the night shift, the first time WLIT has had a local night show in nearly 8 years.
