Read this: Stadium attendances are a significant source of regular income for Premier League clubs. For the 2009–10 season, average attendances across the league clubs were 34,215 for Premier League matches with a total aggregate attendance figure of 13,001,616. This represents an increase of 13,089 from the average attendance of 21,126 recorded in the league's first season (1992–93). However, during the 1992–93 season the capacities of most stadiums were reduced as clubs replaced terraces with seats in order to meet the Taylor Report's 1994–95 deadline for all-seater stadiums. The Premier League's record average attendance of 36,144 was set during the 2007–08 season. This record was then beaten in the 2013–14 season recording an average attendance of 36,695 with a total attendance of just under 14 million, the highest average in England's top flight since 1950.
