KWIZ 96.7 FM "Radio Exitos" was a Spanish station licensed to Santa Ana, California. The call letters were named for the multiple quiz shows which were popular on sister station 1480 KWIZ-AM in the 1950s. KWIZ-FM is currently a Regional Mexican station known as "La Rockola."
Despite broadcasting in southern California, "La Rockola," along with XHTY 99.7 "The Invader" from Tijuana, Mexico, recently showed up in the Arbitron ratings for Middlesex/Somerset/Union, New Jersey. Arbitron ratings are formulated using written diaries as well as data from portable people meters (PPMs) which are pager-like devices that are used to measure how many people are exposed to individual radio stations. Obviously, someone was listening to these California stations in New Jersey via the internet or traveled there while wearing their PPM. It also goes to show how one listener (or a tiny handful of listeners) can impact the ratings.
