The formal pace of Sesame Street over 26 years.

Television producers often use a high rate in the succession of visual and auditory features in their programs to attract the attention of viewers. In this study an attempt was made to measure the formal pace of television programs by scoring the rates of an extensive set of formal visual and auditory characteristics. Sesame Street was chosen as a focal point because this educational program--with its high pace--is very successful in its competition with the majority of commercial programs from which children can choose to watch at home. The analyzed material consisted of 49 Dutch episodes of Sesame Street broadcast between 1977 and 2003. The formal pace characteristics of separate program items from Sesame Street could be reliably established. Factor analysis indicated that clear pace factors were (a) "editing," consisting of a frequent use of different types of shots (total shots, medium shots, and close-ups) combined with a large number of cuts and (b) speech rate. Over a period of 26 years, the pace of editing increased: the mean number of cuts increased from about 4 to 8 per minute. The mean speech rate decreased from 175 to 139 words per minute.
