The name derives from the fact that LPTV stations, like the TV translators that continue to operate, cannot employ transmitter powers in excess of 1,000 watts. This imposes a practical ceiling on the effective radiated power, using a high-gain antenna, of 20 kilowatts or so under ideal conditions. It contrasts with regular, full­ service TV operations, which are permitted up to I00 kilowatts of effective power (channels 2 to 6), 316 kilowatts (channels 7 to 13), or 5,000 kilowatts in the UHF bands (channels 14 to 69). As of the end of 1995, the FCC had licensed 1,787 LPTV stations, with 1,224 operating at UHF, the remainder at VHF. The total number of LPTVs exceeds the number of licensed full-service TV stations in the United States-some 1,180 commercial and 363 noncommercial stations, or 1,543 total.

     Prior to the official launch of LPTV services, the FCC had granted waivers to permit origination of programs in several instances, notably for rural educational programming in upstate New York, and for the satellite-fed bush stations in Alaska, where there was no practical alternative for delivering television programming to isolated villages. The first low power television station was constructed in 1981 by John W. Boler in Bemidji, Minnesota. Boler had been a pioneer broadcaster in Fargo, North Dakota, and built the Bemidji facility as a smaller version of a traditional independent TV station, with regular evening news, studios, a sales force, and even a mobile van.

     LPTV service expanded just as the equipment manufacturers were introducing significant cost and feature improvements for all broadcast components. It became possible for a crew of one to record programs with a camcorder on inexpensive S-VHS cassettes and use them to offer a watchable broadcast picture. Satellite services also expanded, giving LPTV operators a choice of program fare from new networks.

     Mark J. Banks, a professor at Slippery Rock University in Pennsylvania, performed mail and telephone surveys of low power television stations in 1988, 1990, and 1994. In the most' recent survey, his sample of 456 stations yielded completed interviews with only 129, but the results are somewhat informative. Seventy-one percent of the LPTV stations were commercial, 17 percent public or educational, 10 percent religious, and 2 percent operated on a scrambled, subscription basis. A plurality, 40 percent, were in rural areas, but almost as many, 37 percent, were urban, with the remainder suburban or a mixture. The largest "group owners" are Alaska Public Broadcasting and Trinity Broadcasting Network. LPTV was designed to favor minority ownership, but only 8 percent described themselves as minority controlled.

     The surveys over time indicated reduced dependency on satellite-fed program services, in favor of increased local programming. Stations reporting use of satellite services dropped from 87 percent in 1988 to 55 percent in 1994. Conversely, the amount of station time devoted to local programming has grown. The 63 percent reporting local programming said their most popular categories were, in order, sports, news, talk, community events, public affairs, and children's programs. Locally originating stations derive their greatest revenue by far from the sale of local advertising, and total revenue is up to an average of $240,000 per station per year.

     Low power television has achieved a solid niche, providing new services to rural areas that cannot support full-service TV and to ethnic and religious groups in large urban areas. The full-service TV broadcasters, commercial and noncommercial, opposed LPTV from its inception, and sooner or later may succeed in eradicating it. The FCC no longer assigns any priority to ensuring program delivery to underserved audiences and, as of the end of 1995, the agency had made no provision for LPTV in the future to change over to some form of advanced, digitized TV system.
