For most of 2012, KBIG-FM (104.3) has been hot on the heels of its sister station, Top 40 outlet KIIS-FM (102.7), the pop powerhouse that has led Los Angeles-Orange County radio ratings for most of the last three years.
Steve Carney at LATimes.com is reporting in September, the sibling finally caught up, according to figures released Monday by the Arbitron ratings service.
KBIG, the adult-contemporary station that features a varied playlist ranging from Aerosmith to Usher, tied KIIS for the top spot, with each attracting 5.2% of the audience in the survey of listeners 6 and older from Aug. 16 to Sept. 12.
In the previous month, KIIS had taken first with a 5.5% share, while KBIG had come in second at 4.9%. Both are owned by Clear Channel, the nation's largest radio chain, which also operates six other stations in Los Angeles.
A year ago, KBIG — known as "MYfm" — was in 11th place, and sat there as recently as November 2011. But the station jumped to fourth in January, and was in second place by May, where it remained until grabbing a share of the pinnacle in the September survey.
