In 1967, an Audio-Visual Aids Committee was formed under the aegis of the General Board to carry out a survey of facilities in University departments. Over the next five years, it appointed a small number of technicians, based in the Engineering Department, to assist in audio-visual operations, with A.M.P. Brookes, Lecturer in the Engineering Department, as its Head. Its growing Photography outfit was housed in the Old Examinations Hall, Free School Lane from 1974. In 1975, the rest of the operation joined Photography and the Unit was established as an independent University institution reporting to the General Board, supervised by a Committee of Management. Martin Gienke was appointed the Unit's head in succession to Brookes in 1980. Throughout the 1970s-90s, work in support of teaching and learning ranged from the small-scale loan of equipment, advice on purchase and maintenance, to the production of videos and provision of training courses and play-back. The Unit was closed in December 1997. Its slide production and photographic development service was incorporated into the reprographic services of the Computing Service. Video-related services were taken up by CUMIS [Cambridge University Moving Image Studio], 1 Bene't Place, Lensfield Road, established in 1998 under the aegis of the Department of Architecture. CUMIS facilities included digital image and sound capture, and post-production for individuals and workshop groups of up to twelve participants. In [date? after 2004], these services were taken over by the Centre for Applied Research in Educational Technologies (CARET).
