Mr Thompson took heart in the improved performance of DMG's Sydney station. Nova 96.9 bounced back 0.4 points to snare 8.7 per cent of listeners in the last survey. 2DayFM fell more than one ratings point to 10.6. More significantly, 2Day relinquished the coveted number one position in the lucrative 25- 39-year-old demographic to Nova. "We've got to get that back," Austereo chairman Peter Harvie said. "That's one of our key jobs." Austereo shares tumbled 5c to $1.50 yesterday. Austereo managed to claw back some audience from new entrant 97.3FM in Brisbane in the last survey. B105 rose from 17.9 to 20.3. 97.3FM, which is jointly owned by DMG and ARN, slipped from 14.2 to 13.6.
