 When digital terrestrial television was first launched in the UK, it was decided that Multiplex A must carry Channel 5 nationally, S4C in Wales and TeleG in Scotland.The right to operate the multiplex (and therefore the rest of the space) was to be given to the highest bidder.S4C (who were already guaranteed their 'gifted' space on the multiplex), United News and Media and NTL set up S4C Digital Networks (each owned one-third of the company) and bid for the right to operate Multiplex A.
