Global, Bauer, Wireless & everyone else all more or less subscribe to IRN. It’s run by Sky News, but Global oversee the commercial operation.

The Newslink adverts you hear around the top of the hour between 6am and 1pm are all sold/aired for the profit of IRN. Global do the sales and distribute the schedule to stations to ensure they air the correct bits of copy.

Thanks for the clarification. Wasn't IRN owned by the commercial stations in the 1970s?
