major publicity boost by a complimentary article that appeared in the May 24, 1941 issue of The Saturday Evening Post, and eventually hundreds of college stations were established. Responding to the growing phenomenon, a 1941 release issued by the U.S. Federal Communications Commission (FCC) stated that because of the stations' very limited ranges, it had "not promulgated any rule governing their operation." Therefore, to operate legally, U.S. carrier current station broadcast emissions must adhere to the FCC's Title 47 CFR Part 15 Rules for unlicensed transmissions. Educational institution carrier current and cablecast stations Many college stations that went on to obtain FM broadcasting licenses started out as carrier current stations because of the low cost and relative ease of starting one. Although college-based carrier current stations have existed for over 80 years, their numbers are steadily declining, becoming supplemented, or replaced, by other transmission methods, including low-power FM (LPFM), closed circuit over cable TV channels, and Internet streaming audio and video, along with simple PowerPoint presentations of college campus news and information being streamed using low-cost consumer televisions and monitors. As with most other student-run facilities, these stations often operate on sporadic schedules. In the United States, unlike educational FM stations, carrier current stations can carry a full range of advertising. Due to their low power, these stations do not require an FCC license, and are not assigned an official call sign. However, in keeping with standard radio industry practice, they commonly adopt their own call sign-like identifiers.
