the Sheridan Stand at a cost of $8.2 million and was opened in 1986. The old concrete scoreboard was closed in 1983 and a new electronic board erected above The Hill. This board allowed the crowd to see video replays and provided more scope for advertising. The old concrete scoreboard sat behind the Doug Walters Stand unused until 2006 when it was dismantled and stored offsite to make way for the Victor Trumper Stand. The Bob Stand has been moved to North Sydney Oval, replaced by the Bill O'Reilly Stand. This stand was originally named the Pat Hills Stand, after the NSW Labor Government Minister and SCG Trust member, when it was opened in 1984. However, the incoming Greiner Government changed the name to the O'Reilly Stand after the legendary spin bowler. The Hill also has gone but the reason for that is a little harder to pin. Up until 1991 the Hill was a grassy slope without seating. It was the 'outer ground' costing the least to get in and attracting working class patronage. The invention of the beer can and the portable cooler in the 1960s increased alcohol consumption at cricket matches which in turn fuelled bad crowd behaviour. In the 1970s the advent of limited overs games held partially at night attracted a different kind of crowd to cricket at the SCG. They were less interested in the subtleties of the game and more in the excitement and spectacle. Brawling and excessive drinking were features of the crowd on the Hill at this time. Even the introduction of individual seating on the Hill in 1991 failed to completely eradicate crowd misbehaviour. Stricter measures such as banning alcohol were later implemented with greater success. Further developments have taken place in more recent years with the internal reconstruction of the M.A. Noble stand completed in 1994 and the opening of the NSW Cricket Centre in 1997. This facility includes indoor training wickets and administrative offices for Cricket NSW (formerly NSW Cricket Association). In 1999 the original electronic scoreboard was replaced by a new higher-definition video screen. In the 21st century the Hill has been completely redeveloped with a new 12,000 seat Victor Trumper Stand, completed in 2008. This stand brings the SCG's capacity to 46,000 spectators. During the re-development, the 2 original light towers on the hill were replaced and the 4 other light towers were upgraded, a new
