F4 (Flower Four) or JVKV is a Taiwanese boy band consisting of Jerry Yan, Vanness Wu, Ken Chu, and Vic Chou. The group F4 was formed in 2001 after the Taiwanese drama Meteor Garden that they starred in was widely successful. Together they have starred in several Taiwanese drama series and released three albums, Meteor Rain (2001), Fantasy 4ever (2002), and Waiting for You (2007).
In 2007, due to copyright issues, the group changed its name to JVKV, using the descending age of the initials of its members. Other than their home country, Taiwan, they have also attained popularity in other parts of Asia, such as the Philippines, mainland China, Hong Kong, Singapore, Malaysia, Thailand, Indonesia, Japan, and South Korea.
