Looking through the 2022 WRC Factbook. Slightly interesting that Great Britain and Italy have dropped out of the top 10 media markets whilst Croatia and Greece join. This doesn't include WRC+ but does the live stream on eg. BT Sport. Highest audience was Japan - 74m viewers in 2021.

The top 10 WRC+ markets from 2021 are now listed as 'some of the top markets', list remains the same: USA, GB, France, Finland, Italy, Spain, Germany, Belgium, Sweden, Estonia. No Japan, yet Japanese commentary.
