Channel 4 is a British public-service television broadcaster which began working on 2 November 1982. Although largely commercially self-funded, it is ultimately publicly owned; originally a subsidiary of the Independent Broadcasting Authority (IBA), the station is now owned and operated by the Channel Four Television Corporation, a public body established in 1990, coming into operation in 1993.
Channel 4 was established with, and continues to hold, a remit of public service obligations which it must fulfil. The remit changes periodically, as dictated by various broadcasting and communications acts, and is regulated by the various authorities Channel 4 has been answerable to; originally the IBA, then the ITC and now Ofcom. The preamble of the remit as per the Communications Act 2003 states that:
"The public service remit for Channel 4 is the provision of a broad range of high quality and diverse programming which, in particular:
- demonstrates innovation, experiment and creativity in the form and content of programmes;
- appeals to the tastes and interests of a culturally diverse society;
- makes a significant contribution to meeting the need for the licensed public service channels to include programmes of an educational nature and other programmes of educative value; and
- exhibits a distinctive character.
