The Broadcasting Act 1990 is an Act of the Parliament of the United Kingdom, which aimed to liberalise and deregulate the British broadcasting industry by promoting competition; an example being ITV, in particular, which had earlier been described by Margaret Thatcher as "the last bastion of restrictive practices".^[1] The Act was initiated in part due to a 1989 European Council Directive (89/552),^[2] also known as the Television Without Frontiers directive, and came about after the findings from the Peacock Committee.

It led directly to the abolition of the Independent Broadcasting Authority and its replacement with the Independent Television Commission and Radio Authority (both themselves now replaced by Ofcom), which were given the task of regulating the broadcasting industry with weaker powers compared to the previous authority.^[3]

The Act abolished the Independent Broadcasting Authority (IBA) and Cable Authority, which were replaced by the Independent Television Commission (ITC) and Radio Authority.^[3] The ITC began regulating cable television, which was previously the remit and responsibility of the Cable Authority, in addition to terrestrial television from the IBA which only regulated ITV, Channel 4 and British Satellite Broadcasting. Meanwhile, the Radio Authority siphoned off radio broadcasting from the IBA.

It allowed for the creation of a fifth analogue terrestrial television channel in the United Kingdom, and stipulated that the BBC, which had previously produced the vast majority of its television programming in-house, was now obliged to source at least 25% of its output from independent production companies.

Additionally, in the letter of the law,^[3] the television or radio companies rather than the regulator became the broadcasters as had been the case with the IBA before 1964, when it had fewer regulatory powers than it would later assume.

The Act passed through Parliament despite opposition from much of the Labour Party and from some members of the ruling Conservative Party, who saw it as representative of a decline in standards, and on occasions saw it as enabling what was, for them, an unwelcome Americanisation. Notably, Douglas Hurd has since criticised the Act's after-effects, describing it as "one of the less successful reforms of those years". These Conservatives would have described their position as paternalistic as a term of praise, while supporters of the Act would use it against them as a term of abuse. During Tony Blair's tenure as leader, the Labour Party's broadcasting policy generally shifted much more towards that expounded in the Act.

The then Home Secretary, David Waddington, described the Act as heralding "a massive expansion in choice", and supporters of the multichannel age in British broadcasting have praised the Act, and later regulation influenced by it, for such reasons. Supporters of the previous, more regulated system have strongly criticised the Act, and some have blamed it for what they see as a "dumbing down" of British television and radio. Like many other reforms of the Thatcher years, it has a tendency to polarise opinion very strongly. One initially less-obvious effect of the Act was that technical standards ceased to be monitored and enforced by the regulatory body along with the programme content.
