The Central Office of Information (COI) captures data on transmission numbers and estimated airtime value by film and by sponsoring department. Public information films are also assessed as part of wider research on multi media campaigns. COI records an estimated viewing level figure for each transmission of a film, based on the average number of viewers of the station in question across a particular section of the schedule (daypart). Dayparts are broken down as shown in the table.
