to meet the quality standards required on an international level. Therefore, FIVB organizes congress, workshops, courses for referees, coaches and teachers, to promote grassroot volleyball development, such as: Volley All Festival Good Net Project in 2019 School Volleyball Congress in 2007 Volleyball Medicine Congress in 2011 Symposium on Match Analysis in 1981 Symposium on Mini Volleyball in 1985 Another relevant area of concern is the promotion of volleyball in a worldwide scale. Part of the FIVB's activities in this area consists in attracting media partners and sponsors through negotiation of commercial rights for broadcasting and coverage of major events. As reported by Olympic news outlet Around the Rings, the FIVB recently launched a new "FIVB Heroes" promotion in Rome. The campaign uses billboards, posters and statues of the top beach volleyball players situated around the city to enhance visibility and profiles of the athletes. The FIVB is responsible for the standardization of volleyball rules. In recent years, many changes were implemented in connection with its promotional and marketing vision, in an alleged attempt to improve public visibility and make the sport comply to the demands of sponsors and media organizations. These changes range from ingenuous, almost commonplace restrictions, such as the obligation of a "fashionable" uniform – meaning tight clothing, supposed to be more appealing to the audience because it makes players bodies salient –, to very drastic changes in the format of competitions (e.g., the rally-point system). The FIVB is the ultimate international authority in volleyball, and judges (or is involved at least to some degree in the judgement) issues such as doping, regulation of player transfer, nationality changes and gender determination. It also publishes the FIVB World Rankings, used as basis for seeding in international competitions.
