As a public service broadcaster, the ITV network is obliged to broadcast programming of public importance, including news, current affairs, children's and religious programming as well as party election broadcasts on behalf of the major political parties and political events, such as the Budget. The network also needs to produce accessible output containing subtitles, signing and audio description. In exchange for this programming, the ITV network is available on all platforms free to air and can be found at the top of the EPG of all providers.
