There had been only men's singles until the inauguration of women's singles in 1996 and team competitions in 1990. The team competitions, the World Team Cup, were canceled until the relaunch in 2007, and now held in odd-numbered years. The competitions are sanctioned by International Table Tennis Federation (ITTF) and classified as R1 in rating weightings, B2 in bonus weightings in the ITTF world ranking.[1]
