Many unofficial clips from the show can be found on the usual video hosting websites, although the search terms of "Channel 4/Four UK Network 7/Seven" generally result in programme results from Australia's "7 Network", and similar channel names worldwide.
The series had more broadcast experience behind it than it appeared. "Network 7" was produced by Sunday Productions, actually a wholly owned subsidiary of London Weekend Television, which is how the programme archive is now part of the ITV Studios Global Entertainment programme archive. Confusingly, rather than using their own LWT studios (aka "The London Studios"), they decided to use Limehouse Television in London Docklands. During this period, Limehouse Television studios were based in their converted banana warehouse. "Network 7" came from the unconverted part of the warehouse. The series ultimately ended due to re-development of the Limehouse TV studio site which became widely known as the towers of Canary Wharf. (In further inter-linking, Limehouse TV would move into studios at Wembley, that had previously been Studios for Associated-Rediffusion, the early studio base for LWT, before becoming known as Fountain Studios by 2019).
During the time that Charlie Parsons worked on "Network 7", it featured a short running island based elimination competition sub-strand series, entitled "Castaway", that can now legitimately be viewed as the back-door pilot test run of the series format "Survivor" that he would later develop and Executive Produce for various international broadcasters.
Seemingly it was named Network 7, as it was on sundays, considered the 7th day of the week.
The entire run was a live show was 2 hours long every sunday, and on at what was generally considered lunchtime, or breakfast if the audience had been up late the night before. The final episode was a pre-recorded 2 hour compilation featuring items from both seasons, and opened with a steadicam shot around the banana warehouse.
