From its launch until June 1983, programming was primarily based on BBC1 during the daytime, apart from during coverage of major news events which saw the programmes shifted to BBC2.
From the mid 1960s onwards a typical weekday on the BBC and ITV was limited to just 7 hours of normal programming during the day.
[1][2] From September 1960 until October 1973, the presentation was a black and white card with a pie chart split into five segments with a BBC logo in the bottom right corner.
This was accompanied by a similar version for BBC2 with double lined BBC2 logo, for occasions when schools programmes were transferred to that channel.
The spinning Schools and Colleges legend was in fact unintended and was a result of an issue with the mechanical model used[citation needed].
[3] At around this time, special holding captions with the phrase 'Follows Shortly' were beginning to be used for junctions longer than the 60 seconds that the ident required.
All gaps of less than fifteen minutes were now filled using the newly designed 'Follows Shortly' captions over music, before cutting to the ident and announcement.
A later addition was that of a 15-second countdown timer, displaying the seconds in a box, usually located in the top right corner of the screen.
Secondary school programming continued to air during 'Daytime on Two' until Autumn 1999, when it made its permanent move to BBC Learning Zone.
All schools programmes were then shown overnight on the BBC Learning Zone, until the strand ended on 24 July 2015 due to budget cuts.
When the CBBC Channel launched in February 2002, their remit resulted in their need to show schools programming.
