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.^[1] 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.^[2]

The IBA appointed and regulated a number of regional programme TV contractors and local radio contractors, and built and operated the network of transmitters distributing these programmes through its Engineering Division. It established and part-funded a National Broadcasting School to train on-air and engineering staff.

Approach

The IBA's approach to regulation was more robust than that of its successors, and it assumed the ultimate role of the broadcaster (whereas today, TV licensees are termed "broadcasters in their own right"). The IBA took a very "hands-on" approach and placed the interests of the viewer before anything else. For example, if two ITV licensees wanted to merge, or another wanted to change its broadcast name, this would require approval by the IBA. This direct approach extended to programmes also; the IBA could (and did) place limits on how many soap episodes could be shown per week,^{[citation needed]} if they believed programme quality would be compromised.

As well as setting guidelines on advertising content (some guidelines only, the remainder being the responsibility of the ASA), quantity and timings, the IBA also operated monitoring systems for the quality of programme content and the technical quality of programme play-out.

There were also limits on the value of prizes that could be given away – this dated from the broadcast of the UK version of Twenty-One in 1958 in which a contestant won enough money to buy both a car and a house.^[3] In 1960, two years after the scandal in America, the Independent Television Authority (predecessor of the IBA) imposed a £1,000 cap on the value of prizes; this increased over the years to £6,000 in 1981, and was abolished in 1993. British versions of popular American quiz shows had to be adjusted – The $64,000 Question having a maximum prize initially of 64,000 sixpences (£1,600) in the late 1950s, and in the early 1990s of just £6,400. "The Six Thousand Four Hundred Pound Question" was only asked every other week, so as not to break the regulatory £3,200/week maximum.

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.

1980 franchise round

Regional programming on ITV was a major concern for the IBA, particularly in the 1980 franchise round. The IBA was determined each franchise provided the best possible local service, so the South of England transmission region was split in two, with the successful applicant required to provide separate news services for the South and South East, while in the Midlands ATV's commitment to regional output in the Midlands had been a long-running issue for the IBA; in 1980, they were allowed to keep their franchise, but with several tough conditions.

Engineering advances

The Experimental and Development Department, as part of the IBA's Engineering Division, was responsible for much leading edge research into broadcasting technology as well as being responsible for the design and manufacture of specialist equipment that could not be procured from commercial manufacturers. In particular, the IBA's E&D Department developed SABRE (Steerable Adaptable Broadcast Receiving Equipment) that enabled mainland broadcast television channels to be received for re-broadcasting in the Channel Islands. During the early 1980s, the E&D Department designed and manufactured the specialised broadcast receiving and monitoring equipment used to build the national broadcast network for Channel Four. Subsequently, E&D's engineers proposed a system of analogue television encoding known as MAC (Multiplexed Analogue Component) to provide a standard for the forthcoming satellite television broadcasts that was more robust than an extension of the existing PAL system used for terrestrial broadcasts. E&D's engineers also designed and built some of the first digital audio equipment for satellite broadcasting including systems using data packets. E&D's engineers made many important contributions to digital television data-rate reduction whereby the encoding of a standard analogue PAL colour signal requiring some 130 Megabits/second has been reduced to less than 4 Megabits/second as used on current digital television broadcasting.

Satellite broadcasting

In the late 1980s the IBA was appointed as regulator and transmitter operator for the first DBS (Direct Broadcasting by Satellite) service for the UK and awarded the franchise to BSB (British Satellite Broadcasting). In advance of this, the rival Sky Television plc was able to launch an analogue service and intended to overshadow BSB by leasing transponders from Société Européenne des Satellites' RCA Astro-built satellite, Astra 1A. After around a year, the company merged with BSB.

Succession

The IBA was disbanded as part of the Broadcasting Act 1990, being replaced on New Year's Day 1991 by the Independent Television Commission (ITC) (which also absorbed the Cable Authority), and the Radio Authority (RAu), which have since been merged with other regulators such as Broadcasting Standards Commission (BSC) and Oftel (Office of Telecommunications) to form one regulator, Ofcom. All of the IBA's engineering function, except for a limited number of Quality Control engineers, was transferred to a newly set-up private company, National Transcommunications Limited (NTL), which continued to run the former IBA transmitter masts. These assets are now within the portfolio operated by Arqiva. In 2008 the IBA's extensive archive was lodged with the University of Bournemouth.^[4]

The IBA's Membership of the European Broadcasting Union was passed to United Kingdom Independent Broadcasting (UKIB).

Such was the sense of purpose and camaraderie amongst former employees of the IBA that they still meet up near Winchester for an annual reunion in late January, typically boasting an attendance of over fifty.^{[citation needed]}

Technical publications and legacy

The engineering staff of the IBA contributed many papers to international standards groups and conferences over many years. The IBA also operated an Engineering Information service in support of the receiver industry and the general public offering information and advice about the transmitter networks and reception issues. Its lasting legacy is a set of IBA Technical Reviews published over a period of 16 years from 1972 to 1988. The complete set of these Reviews as well as some other documents and records is available for free download.^[5]

The reviews were primarily written by the technical staff of the IBA but some articles were written by others from the Independent Television companies and by external specialists. The first volume was published in September 1972 when the Engineering Division was located in Brompton Road, London prior to its move to Crawley Court near Winchester in 1973. Other members of the Division manned the transmitting stations and maintenance bases spread across the UK. The series ended with the 24th volume published in November 1988. One reason for the termination of the publications was the abolition of the IBA in 1990 and the subsequent privatisation of the Engineering activities as National Transcommunications Limited [NTL]; the government white paper proposing this was published in the autumn of 1988.

These Reviews are valuable in recording the activities of the various Departments of the Division during a period of considerable change in broadcasting. IBA staff members were active not only in designing, building and operating transmitter networks they also made significant contributions to new digital broadcasting standards and their implementation. The laboratories of the IBA were in the forefront of the development of digital television technology, as can be seen in some of the reviews but, after the abolition of the IBA, NTL continued to contribute significantly to the development and implementation of the successor technology that underlies modern Freeview transmissions.

Copyright in these documents originally vested in the IBA. On its abolition, its assets were distributed between the Independent Television Commission [ITC] and NTL, each of which has subsequently been absorbed by other bodies. The ITC was absorbed by OfCom and the original NTL has evolved into an independent company, Arqiva. The copyright is now vested in OfCom.
