Founded with the name of Sport -Club Juventus, initially as an athletics club, it is the second oldest of its kind still active in the country after Genoa 's football section (1893) and has competed uninterruptedly in the top flight league (reformulated as Serie A from 1929) since its debut in 1900 after changing its name to Foot - Ball Club Juventus, with the exception of the 2006–07 season, being managed by the industrial Agnelli family almost continuously since 1923. The relationship between the club and that dynasty is the oldest and longest in national sports, making Juventus the first professional sporting club in the country, having established itself as a major force in the national stage since the 1930s and at confederation level since the mid- 1970s and becoming one of the first ten wealthiest in world football in terms of value, revenue and profit since the mid- 1990s, being stocked in Borsa italiana since 2001.
Under the management of Giovanni Trapattoni, the club won 13 trophies in the ten years before 1986, including six league titles and five international titles, and became the first to win all three competitions organised by the Union of European Football Associations: the European Champions' Cup, Cup Winners' Cup and UEFA Cup. With successive triumphs in the 1984 European Super Cup and 1985 Intercontinental Cup, it become the first and thus far only in the world to complete a clean sweep of all confederation trophies; an achievement that they revalidated with the title won in the 1999 UEFA Intertoto Cup after another successful era led by Marcello Lippi, becoming in addition the only professional Italian club to have won every ongoing honour available to the first team and organised by a national or international football association. In December 2000, Juventus was ranked seventh in the FIFA 's historic ranking of the best clubs in the world and nine years later was ranked second best club in Europe during the 20th Century based on a statistical study series by the International Federation of Football History & Statistics (IFFHS), the highest for an Italian club in both.
The club's fan base is the largest at national level and one of the largest worldwide.
