Blizzard is obviously proud of the Warcraft series and as such they opened a World of Warcraft Anniversary Website. World of Warcraft is celebrating 5 years and Warcraft 15 years of huge success.

Here's what they have to say:

World of Warcraft Turns 5! Warcraft Turns 15!

Over the past five years, a lot has changed in Azeroth. Valiant heroes have travelled the length and breadth of Kalimdor and the Eastern Kingdoms, taken wing in Outland to free the Black Temple from Illidan's clutches, and set sail for Northrend to battle the mighty Lich King. Whether you've been part of the adventure from the beginning or are just getting started now, we're glad to have you with us for the five-year anniversary of World of Warcraft and the 15-year anniversary of the Warcraft series.

Over the next few weeks, we'll be updating our website with a series of anniversary interviews and features that take a look at World of Warcraft and the Warcraft series through the eyes of the people who've created, played, and lived the games. We're honored to be celebrating this milestone with a community of players every bit as passionate about the game as we are. We hope you enjoy the journey.
