Siwon - Super Junior 110000 units

Hanteo Chart recently released sales figures for the first half (first 6 months) of 2009 and Super Junior's album"Sorry Sorry," which was released in March came out on top with sales of 110,000 units.
Fellow SM Entertainmentmembers SNSD / Girls' Generation came in second with their January release of "Gee," which sold 75,000 units.
Legendary singer Seo Taiji came in third with "Seotaiji Atomos Part Secret" selling 59,000 units.

With TVXQ / DBSK / Tohoshinki doing sales of over 350,000 for "Mirotic" (not including the over 330,000 preorders for the album) and having top sales for 2008,
it seems SM Entertainment has been dominating the charts. It looks like that trend will continue in 2009
