Stadium, home of Bradford Bulls, and has a capacity of 27,500. There is no national stadium for rugby league in England. Despite this Wembley Stadium is annually used as the venue of the Challenge Cup Final, and Old Trafford as the venue of the Super League Grand Final. The Super League's Magic Weekend is used to promote rugby league to a wider audience. The Millennium Stadium, Murrayfield, Etihad Stadium, St James' Park, and Anfield have all be used to host the event. Popularity Rugby league is the fourth most popular team sport in England. Historically, rugby league has been the second biggest spectator sport in England with 6.8 million spectators attending the 1948–1949 English season. Rugby league is most popular in its traditional heartlands and, in those areas, interest in the sport can rival that of association football. Many large towns with rugby league traditions do not have football teams as a result of the monopoly on local interest: these towns include, Keighley, Castleford, Dewsbury, Batley and Wakefield. The regions in which rugby league is played most are Cumbria, where the amateur version has a high participation rate, former traditional Lancashire regions Merseyside and Greater Manchester, Yorkshire and Cheshire. There is also significant schools participation in London. Many of the professional and semi-professional teams are connected by the M62 motorway and so the term "M62 corridor" is sometimes used to refer to the area where rugby league is most popular. An old survey from 1994 showed that back then, sixty per cent of people regularly attending rugby league lived in only four postal districts along the M62. The sport has since launched several expansion teams in the south. Fifty per cent of viewers who watch rugby league on Sky Sports live in the South of England. Over 40% of active rugby league supporters are female. At the beginning of the 2006 season there were between thirty and forty female-only rugby league clubs running in England, not including clubs that have teams of both sexes. The majority of these clubs are located in Lancashire and Yorkshire. Rugby league has for much of its history been banned in the armed forces and in many schools and universities, further stifling growth. These barriers have largely been dismantled since professionalisation of rugby union. The 2006 Super League generated the highest weekly average attendance in the 11-year history of the competition.
