 Opting out was also common throughout telethons, such as "Children in Need", where regions separate to transmit local coverage.The term "opt-out" is a peculiarly British idiom when applied to broadcasting, while used to describe the occurrence of regional events in an otherwise national stream the term has fallen into technical misuse.Of the British broadcasters, really only the BBC ever opts out within the proper technical meaning of the term and then only in its English regions.
