The game maker Konami announced on Tuesday that Guinness World Records has recognized Yu-Gi-Oh! as the best-selling trading card game to date with over 25,175,567,833 cards sold as of March 31, 2011. The card franchise beat its own record of 22,587,728,173 cards, set in 2009 that include the Anime, Manga , Games and 10th anniversary Movie also its card franchise.
"Proof of Guinness Record"
Kazuki Takahashi drew the original manga from 1996 to 2004, and it spawned an ongoing anime franchise in addition to the cards. The card game first shipped in 1999 and eventually spread to over 45 countries in North America, Europe, and elsewhere. Konami had first applied for the record back in 2006, when "only" 15.8 billion cards had been sold.
Well The New Yu-Gi-Oh! Series "Zexal" might improve or beat the record if it become more popular than their Previous Series in Anime, Manga and Games lol^^.
