The Independent Broadcasting Authority (IBA) was the regulatory body in the United Kingdom for commercial television (ITV and Channel 4 and limited satellite television regulation – cable television was the responsibility of the Cable Authority) – and commercial and independent radio broadcasts. The IBA came into being when the Sound Broadcasting Act 1972 gave the Independent Television Authority responsibility for organising the new Independent Local Radio (ILR) stations. The Independent Television Commission formally replaced the IBA on 1 January 1991 in regulatory terms, however the Authority itself was not officially dissolved until 2003.
For several years until July 1990 the IBA put out a short weekly programme under the title Engineering Announcements, transmitted outside normal programme hours, and not otherwise advertised. These provided valuable technical information for members of the radio and television trade. The images on this page are from these announcements.
