  • 2004: First Lansing-area station to broadcast digital programming and the first college station in the USA to offer digital broadcasts.
  • WDBM is the evolution of what once was believed to be the country's largest carrier current network with studios located in various MSU dormitories. After those stations consolidated into WLFT, the station received its license to broadcast on FM in about 1989 and subsequently shut down the carrier current operations of WLFT.
