Television was not created by a single inventor; many people working together and alone over the years have contributed to the evolution of television. Developments often take several years before they become mainstream.

UK television has one of the most regulated sytems in the world. Ofcom is the independent regulator and competition authority for the communication industries in the UK. It received its full authority in the Communications Act 2003, and inherited the duties that had previously been the responsibility of five regulatory bodies:
It has a statutory duty to further the interests of citizens and consumers by promoting competition and protecting consumers from harmful or offensive material. It deals with licensing, undertaking research, creating codes and policies, addressing complaints and looking into competition. It organises public consultations, holds public meetings and interviews individuals.
When Ofcom receives a complaint it asks the broadcaster for a copy of the programme and any response. It then examines the programme to see whether it is in breach of the Broadcasting Code, marking the complaint as either upheld, upheld in part, not upheld or already resolved (where an error has already been dealt with).
