 The extension of Best 104's broadcast into THR's Klang Valley listener hinterland in 1996 presented a challenge of sorts to THR, with at least one deejay 'leaping' from THR to Best 104.However, it was the start of AMP Radio Network's HITZ FM broadcast in January 1997 that really hurt the popularity of THR, as it did Best 104.Introduction of further English stations by AMP Radio Networks eroded the English listenership of both stations (THR and Best 104), upon which advertising revenues of both were largely dependent.
