Normally, for a company to have shipped 10 million of a certain line of products, we're excited and impressed. But think about it. This isn't 10 million worldwide, this is 10 million shipped in South Korea. Now obviously, it's to be expected, since Samsung's home is in South Korea (along with LG's). But it's still pretty crazy.
The Galaxy Note line kicked off in 2011, at IFA in Berlin. The first Galaxy Note was really only available outside of the US. It did make it's way into the US on AT&T months later and was slated for T-Mobile but it was only on sale for about a week or so. Then came the Galaxy Note 2 at IFA 2012 in Berlin. Which Samsung put the Galaxy Note 2 everywhere, and I mean everywhere. It launched on Verizon, Sprint, T-Mobile, AT&T, and US Cellular within 2 months of announcement, and the Note 3 was like deja vu. The Galaxy Note 3 also launched on all five major US carriers within 1 month of the announcement. So it's really no surprise that Samsung has sold 10 million Galaxy Note devices in South Korea.
Why is the Galaxy Note so popular in South Korea? Well one major reason is probably because those in South Korea want to support their manufacturer that is in South Korea, but also the large screen, the S Pen, and all the other many features included in the Galaxy Note devices, which there are plenty more than there were with the original Galaxy Note. Now some may call these features "bloat" or stuff you don't need. Which is understandable, as there really is a whole lot of features in the Galaxy Notes, some may use all the features, some may not. But the great thing about Android, and even Touchwiz to an extent, is that you can disable many of those features.
Samsung has decided they want to celebrate this milestone, which I can't say I blame them it's a great milestone. They are offering customers a chance to win tickets to a musical or even a camera.
