More TV coverage too.
In 2004, there were only 7 TV events between the PDC and BDO IIRC. (Lakeside, PDC Worlds, UK Open, Desert Classic, Matchplay, Masters, Grand Prix)
In 2024, there will probably be 12 between the PDC and WDF. And that's not accounting for the individual PL fixtures or WS support events. Neither the expanded fields in both versions of the World Championship equating to more games. Nor the Seniors events.
Funnily enough, I remember seeing Taylor's first TV 9 darter (2002 Matchplay), but I have zero memory of seeing his second (UK Open 2004). I'd pretty much forgotten about it until you posted that video.
