The program premiered in first-run syndication on September 13, 2004 and ended on September 9, 2017, as a spin-off of Entertainment Tonight, which originated the concept as a segment that took viewers "behind closed doors" and gave them "inside" information on stories and topics of interest from throughout the entertainment industry. When it became a separate program, it shifted toward a tabloid direction, and had several format changes throughout its thirteen seasons on the air before settling on a final format at the start of the 2011–12 season, when shed many of the tabloid elements and became more of a straight rundown of entertainment news, providing coverage of events and celebrities, interviews and inside looks at upcoming film and television projects. The program's weekday broadcasts were anchored by Louis Aguirre and Debbie Matenopoulos; its weekend editions were anchored by Michael Yo and Keltie Knight, who also served as correspondents for the weekday editions.
