HITZ FM was launched into Malaysian FM airwaves in January 1997 after being one of Astro's audio-only channels since the launch of the satellite network in October the year before.
In 2000, the Malaysian Top 10 (later renamed Malaysian English Top 10) was introduced, airing every Sundays at 4pm to bring the limelight into local Malaysian music which would suit the tastes of hitz.fm's listeners, especially indie acts.
In April 2001, HITZ FM was rebranded as hitz.fm (with a dot) as an emphasis of its significant Internet presence for its listeners rather than just being a radio station, providing online facilities like webcasts of their announcers in action as well as radio streaming.
In August 2003, a rift between Li'l Kev and the management of AMP over the contract between them caused him and FlyGuy to leave hitz.fm abruptly. Jason Lo and Rudy Sufian were called up to fill in their places and eventually became the new Morning Crew. (Later, Lo switched time slots with JJ Fernandez for the drive-home slot). Later in the same year, HITZ.TVwas launched as a complement to the radio channel.
In 2005, the hitz.fm Malaysian English Top 10 Awards was introduced to honour the best of Malaysian English-singing musical talent and compositions. Two such events have held thus far.
In 2008,Rudy announced his decision to give up his morning show.Rudy confessed to having problems getting up in the mornings and needed to change his work pattern.With the new schedule(The new hitz.fm morning crew), JJ now has a new co-partner Tengku Mohd Ean Nasrun, better known as Ean.
In September 2010,Airtime Management and Programming (AMP) is launching three of its radio channels in East Malaysia. ERA, MY FM & hitz.fm will run from the hearts of Kuching beginning 25th October 2010 and Kota Kinabalu beginning 1st December 2010.
