The broadcasting act stated that advertising content was not to exceed 10 minutes in every hour and commercial breaks during programmes were limited to a maximum of three per hour. Initially all commercials were supplied on 16mm film and were spliced into programme reels. To satisfy the retail market slide/camera card commercials with durations of 7 secs, 15 secs and 30 secs with pre-recorded voice over or live by the duty announcer were also broadcast during these breaks. Retail advertisers were also accommodated with an advertising magazine (Admag) programme broadcast live during early and later transmission times. Admags ran for a maximum of 10 minutes with a series of advertisers grouped into a mini programme. Programmes were hosted by a presenter and many of these presenters later went on to further their television careers hosting local TV programmes.
