The new "Independent Television" network, named due to its independence from the BBC which until then had a monopoly on broadcasting within the United Kingdom, was made up of numerous companies providing a regional television service and would also generally provide programmes to the network as a whole. Each individual company broadcast on 405-line VHF and was responsible for providing a local service, including daily news bulletins and local documentaries, and for selling advertising space on their channel: this measure ensured that all the ITV companies were in competition with each other and that no single broadcaster could gain a monopoly over commercial broadcasting. However, national news was not provided by the individual companies and was instead provided by Independent Television News (ITN). Each regional service had its own on-screen identity to distinguish it from other regions, since there was often a sizeable overlap in reception capability within each region.
