Where the data covers
Coverage regions come from the competitions the provider lists on its own pages (USA = NFL, NBA, MLB, NHL, MLS or NCAA; UK & Ireland = UK/IE racing, Premier League, EFL, Scottish football, UK/IE darts, snooker or cricket; Australia = AFL, NRL, Australian racing or competitions; International = anything else). They are not where the company is based.
