Clubs were founded as that party grew in size in the 1920s. Generally, Conservative Clubs did not join, as they formed their own federation (though there are some such venues still in existence). Servicemen returning from the Great War would also found clubs, and Roman Catholic parishes had clubs. The only stipulation demanded for membership of the CIU was that clubs be owned by the members and accept the standards of membership, as they were often subject to inspection. The wealthier clubs have sports pitches and dining facilities, as well as indoor games and entertainment. Many entertainers developed their skills in them over the years, as depicted in the ITV series The Wheeltappers and Shunters Social Club. Until 2004, the CIU had its own beer brewed by the Federation brewery in Dunston, Tyne and Wear. Although CIU-affiliated clubs do still receive discounted beer, these discounts are largely passed on to the members, and Federation beer will generally be cheaper than beer available in local pubs. The brewery was taken over by Scottish & Newcastle in 2004 and now brews Newcastle Brown Ale. Together with other club organisations such as the Royal British Legion, the Association of Conservative Clubs, the National Union of Liberal Clubs and the National Union of Labour and Socialist Clubs, the CIU is part of CORCA (Confederation of Registered Club Associations) which lobbies Parliament on behalf of clubs. This group was active in the debate about smoking: as most clubs are known for working men who like to drink and smoke (in many cases without any women in the bar), there is some concern about the future prospects of clubs. The CIU holds a national congress every year and as part of its activities runs convalescent homes. In many ways, it could be said to be the oldest surviving friendly society still run by its members, and continues to play a part in the cultural life of working-class families. Today The Working Men's Club and Institute Union is now the largest non-profit-making social entertainment and leisure organisation in the UK, representing the interests and views of six million club members. The Working Men's Club and Institute has come a long way since 1862. However, it could be said that working men's clubs have suffered from an old-fashioned image among young people, and have found it hard to compete with modern trends, resulting in many closures of clubs
