Looking back on the top selling anime series of the 21st century by year, you'll find some shows you'll expect to see, and some you might not have even thought about since they came out. Let's look back and see what shows sold the most in their years.

What's the best way to gauge the success of an anime series? Different factors come into play, from TV ratings to merchandise sales, but one of the most significant ways the anime producers make money is through DVD and Blu-Ray sales. Not every major hit anime is going to sell tens of thousands of DVD volumes. Given the expensive pricing and low episode count of your typical Japanese home video release, extremely popular but extremely long running shows like One Piece aren't going to top disc sales even as they top ratings and merch sales. The shows that do top the sales charts tend to be ones with a set episode count and a dedicated hardcore fanbase. Many of the biggest hits are mecha or moe series, though certainly not every show in those genres is a guaranteed hit. Looking over the top selling anime of the year for each year this century (2015 excluded as those shows haven't all been released to completion, though it's looking like Mr. Osomatsu is going to be the big surprise top-seller), it's fascinating to see which mega-hits are on their way to classic status and which ones have fallen out of popularity since their initial hype.
