Document 5: WRIU: When the station first signed on in 1964 (located at 91.9 on the dial at that time) WRIU's music format was mostly jazz, classical, some folk music, and easy listening. The station signal was 10 watts and coverage was generally just nearby to the Campus, sometimes reaching farther. When the station wished to expand in about 1971, installing a more powerful signal with updated facilities, the U.S. Federal Communications Commission (FCC) requirements included surveying the current and potential audience- mostly URI students- to show support for FCC approval of such expansion. A music listener survey was conducted by WRIU staff, collated, and results were published to help establish a new format based on the survey of listener preferences. This helped WRIU gain the support of URI students and the URI Student Senate, which voted to fund the purchase of equipment for expansion by about 1972. The new music format that was established in 1971 was unique in Rhode Island and continues, flexibly now inclusive of many new musical influences.
