'90s on 9

The '90s on 9 (or just The '90s) is the name of Sirius XM Radio's 1990s commercial-free music channel. The service signed on September 25, 2001 and broadcasts on Sirius XM channel 9, as well as on Dish Network channel 6009. It was also on heard DirecTV channel 806 until February 9, 2010. On November 12, 2008, it was added to Sirius, replacing the original Pulse on Sirius channel 9, whereas the new Pulse, formerly Flight 26 was added to channel 12 on the Sirius side. This is Sirius's first all-1990s channel since I-90 signed off on November 4, 2002. The old Pulse carried a 1990s & hot AC hybrid, whereas the new Pulse just carries modern AC music. In addition, it also replaced the online-only Super Shuffle channel on Sirius, last heard on satellites in mid-2008. On February 3, 2014, the channel became jockless when both Jo Jo Morales and KT Harris were let go in a cost-cutting move. It remained jockless until May 26, 2015, when former MTV VJ Downtown Julie Brown, who also hosts the weekend's "Back In The Day Replay Countdown," began hosting the channel on a daily basis.

The channel focuses mostly on hit-driven R&B, Hip-Hop, Rhythmic, Dance, Rock, Teen Pop, Pop, and Alternative tracks from the 1990s. Many of the station IDs are spoofs of movies, TV characters, songs and TV commercials that were popular during the '90s. Occasionally, lesser-known '90s songs are played, preceded by the 5 CD Changer set on random tagline.

The station logo features a compact disc in place of the zero, representing the rise of CDs in the nineties.
