The three-hour show is hosted by Stephanie Miller and is syndicated by Westwood One. Voice artist Jim Ward formerly co-hosted the show and is a recurring guest. Miller is frequently joined on the air by executive producer Jody Hamilton and general manager Chris Lavoie. The show debuted on September 7, 2004 and is broadcast live from Los Angeles, California each weekday morning from 6:00 a.m. – 9:00 a.m. Pacific Time, on Pacifica station, KPFK in LA, and radio stations throughout the U.S., as well as online, and via SiriusXM Progress Channel 127.
