Broadcasters:
Most broadcasters will likely not care when the World Cup takes places due to the commercial revenue it brings.
Interestingly, the main broadcasters of South America and the US, Fox and Telemundo, were both firmly against the move to a winter tournament as it would impact on an already stocked up calendar and would see audience figures likely affected due to clashing with other sport
Strangely, or perhaps not if you’re as cynical as we are, both Fox and Telemundo both received TV rights extensions to 2026 without so much as a bidding process.
Affects on world football:
In England, the Premier League’s winter fixture list would be frankly impossible now and it may even affect the Football League’s ability to complete their hectic programme in time.
It was calculated by a former head of the Chilean FA that around 50 leagues in the World could be affected by the Qatar World Cup due to the required changes in the calendars of 2021/22, 2022/23 and 2023/24.
The African Cup of Nations in 2022 would also likely be moved to the middle of the year.
