This study surveyed musical productions acquired by National Educational Television (NET) since its inception in 1952 in order to report their nature, circumstances of their acquisition, and their relative usage. Data were obtained primarily from interviews with persons involved in educational television and from detailed examination of NET files and records. These were among the findings: (1) most single programs were intended as entertainment, while most program series were instructional to some extent; (2) significant program producers and sources include affiliated NET stations, independent American producers, foreign producers, American universities, private corporations, and NET itself; (3) some NET program acquisitions have rights of use for an indefinite period, while others are subject to contracts with performers' unions or to other types of limitations; (4) productions featuring straight performance averaged 12.1 rentals per year, followed by productions featuring musical personalities (11.4), performance with instruction (10.7), and didactic programs. Recommendations on program planning and use were made to NET and to the music education profession. (author/ly)
