Radio Joint Audience Research Limited (RAJAR; /ˈreɪdʒɑːr/) was established in 1992 to operate a single audience measurement system for the radio industry in the United Kingdom. RAJAR is jointly owned by the BBC and Radiocentre. RAJAR's predecessor was called Joint Industry Committee on Radio Audience Research (JICRAR; /ˈdʒɪkrɑːr/). Prior to this, the BBC and Radiocentre's predecessor CRCA carried out their own measurements independently of each other.
