I've had a closer look at the Brisbane radio ratings and noticed something interesting about B105. The former No.1 station, which has been in rebuilding mode this year, is defying the common trend and building audience share through the day. Normally a big commerical station strives to have a huge audience at breakfast time and then tries to hold on during the day. B105 does lose a little of its audience share in the middle of the day, but builds to quite a respectable share in the drive shift (a networked show starring Andy Lee and Hamish Blake). Its (also networked) Hot 30 show at night has one-and-a-half times the breakfast audience share (although, given that fewer people are tuned-in at night, actual listener numbers are probably lower).
