The coronavirus pandemic resulted in Premier League clubs reporting a fall in revenue for the first time, according to finance company Deloitte.
The figures relate to the 2019-20 season, when the top-flight campaign was halted in March 2020 before resuming without fans in June.
Revenue dropped by about 13%, although the 20 Premier League clubs still brought in a combined £4.5bn.
There was also a cumulative pre-tax loss of nearly £1bn.
That is the largest in Premier League history and almost five times the previous season's £200m figure.
"The decrease in revenue in the 2019-20 season is, unsurprisingly, down to the global economic and social disruption caused by the Covid-19 pandemic and will continue to have a heavy impact on the 2020-21 season's financial results when available," said Dan Jones of Deloitte's sports business group.
