All companies holding a licence were part of the non-profit body ITV Network Limited, which commissioned and scheduled network programming, with compliance previously handled by ITV plc and Channel Television. However, due to amalgamation of several of these companies since the creation of ITV Network Limited (and given Channel Television is now owned by ITV plc), it has been replaced by an affiliation system. Approved by Ofcom, this results in ITV plc commissioning and funding the network schedule, with STV and UTV paying a fee to broadcast it. All licensees have the right to opt out of network programming (except for the national news bulletins), however many do not due to pressures from the parent company or because of limited resources. Prior to the affiliate system being introduced, STV would frequently (and sometimes controversially) opt out of several popular network programmes – such as the original run of the first series of "Downton Abbey" – citing the need to provide more Scottish content to its viewers.
