Beyblade

Beyblade (ベイブレード Beiburēdo) is a spinning top toy developed and manufactured by Takara starting in 1999/7.
The introduction of the toy in Japan corresponded with the broadcast of an anime
television series of the same name. In 2002, Hasbro began to sell Beyblade toys
internationally (under license from and produced by Takara) along with a coordinated
country by country roll-out of localized versions of the TV series. The Beyblade
toy line went on to be one of the most popular toy lines in the world from 2000-2005
and as of 2005 over 100 million units had been sold worlwide. (Wikipedia)
