History of soccer football

Where football comes from Kicking-a-ball games are ancient. China's cuju dates back more than two thousand years, and the Romans played harpastum. In medieval Europe, whole villages played chaotic "mob football" with almost no rules. The modern game starts in 1863, when clubs in London founded the Football Association and wrote a common set of rules. That is also the moment football and rugby went their separate ways. Organised competition followed quickly: 1871–72: the FA Cup, the oldest football competition in the world 1872: the first official international, Scotland vs England in Glasgow, a 0-0 draw 1888: the Football League, the first professional league 1904: FIFA founded in Paris Defining moments 1930: the first World Cup, in Uruguay. The hosts won it. 1950: the "Maracanazo". Brazil needed only a draw at home and lost the deciding match to Uruguay in front of a huge Maracanã crowd. 1954: the "Miracle of Bern", when West Germany beat the gre...

When was basket ball invented

Basketball in Sport Origins and history Basketball is one of the few major sports with a known inventor and birth date. In December 1891, James Naismith, a physical education teacher in Springfield, Massachusetts, needed an indoor game for his students during the winter. He nailed peach baskets to a gym balcony and wrote down 13 rules. The game spread fast through YMCAs and colleges. Basketball became an Olympic sport for men in 1936 and for women in 1976. The NBA's roots go back to 1946, and the modern league grew from its 1976 merger with the ABA. How the game grew worldwide The 1992 "Dream Team" at the Barcelona Olympics is often seen as the moment basketball went truly global. Since then, players from Europe, Africa, Asia and Australia have become stars in the NBA, and the game is now in every region of the world. Leagues like EuroLeague, the Spanish ACB and the Australian NBL have built their own strong followings. Sport business Basketball is a major business. I...

Tennis terms

Image
Tennis is a racket sport played between two players (singles) or two teams of two (doubles). Players hit a felt-covered rubber ball over a net on a rectangular court, trying to land it where the opponent can't return it. How it works A point starts with a serve, and the players then rally until someone fails to return the ball within the court, hits it into the net, or hits it out. Points are counted 0 (called "love"), 15, 30, 40, then game. A player must win by two points, so a tied score at 40-40 is "deuce." Games make up sets, usually first to six games with a two-game margin, and sets make up a match, typically best of three or best of five. Court and surfaces The court is 78 feet (23.77 m) long, with a net across the middle. The main surfaces are hard court, clay, and grass, and each changes how the ball bounces and how fast play is. Clay is slower with higher bounces, while grass is faster with lower bounces. Professional tennis The sport is best kno...
