ABC Television's huge outside broadcasting fleet gave the company an advantage in sports production that no other company in ITV could match.

Its vans would travel the length and breadth of England to capture sports events for the Saturday morning programme 'World of Sport'.

But this still left some hours of sport "in the can" every week that ABC did not have the broadcasting hours for during the weekend.  The solution was a simple one - sell that material to the weekday companies.

But whilst Rediffusion London may have been the only one of the Big Four not to compete in any way with ABC, thus making their relations friendly but distant, ATV and Granada did compete.  Granada shared a region with ABC, whilst ATV also shared a region but additionally had ABC as a cross-region competitor on weekends.

Neither company was much thrilled at the idea of 'muddying the waters' between the weekend and weekday contractors, so various workarounds were found.  One was in the midlands, where the 7-day per week epilogue was made at ABC/ATV's joint Alpha Studios.  To avoid one programme being made by different companies on different days, the programme was credited to the studio.

In the case of wrestling, the workaround was to drop the ABC name entirely, and to pretend that the programme was an 'Independent Television Presentation', thus neatly hiding all the problems of competing companies under one throw-away brand.
