Town are the second most popular Championship team amongst Sky Sports subscribers, according to figures released by the satellite broadcaster.
Sky looked at which Championship teams had been watched on three or more occasions by 500,000 subscribers in 119 postcode areas since January last year.
Derby County were the most watched club in 82 of the 119 regions with the Blues most popular in 10 and joint-third Leeds and Middlesbrough in eight.
In addition to a stranglehold on East Anglia - including Norfolk - the Blues also appear to have strong fanbase in the West of Scotland. The full chart can be found here.
Matt Roberts, head of sports and news research at Sky, said: "The majority of Championship fans tuning in to watch Championship games live on Sky were from the older generation, and Derby have figured in England's top two tiers since 1992/93 and were prominent in the old First Division throughout the 70s.
"However, what was surprising was the Rams' overwhelming majority of support across the UK. Many people expected Leeds, in particular, to win a considerably higher number of regions.”
