Block B's comeback mini-album, "New Kids on the Block", previously sold out in pre-orders, leading representatives to observe how their actual debut would fare.  Living up to the anticipations, Block B has managed to completely sell out their first batch of productions, ranking second in album sales in just the first week of its release. On this week's 'Gaon' album sales chart, the boys trailed right behind 2PM, who placed first with "Hands Up", which is definitely an exceptional case for a rookie group. Representatives were surprised at the rookie's ability to play right up there with Hallyu stars, and acknowledged their growing popularity. - So what's the secret behind their success? Their label, Brand New Stardom, highlighted the influence of the Hallyu wave. Cho PD explained, "It took 50 days for them to garner over 5,000 fanclub members and just a day for their official Facebook to get 13,000 clicks from all over the world. They've doubled what took Korea 50 days to achieve in just under a day." SNS is the strongest platform for the current K-pop market. Music programs, music videos, and digital releases are spread all over the world from the moment of its release, which helps greatly in gathering a fanbase. Cho PD mentioned that the data collected from YouTube and Facebook helps in understanding the group's current position, and fans through other services like Tumblr help spread awareness through their own SNS accounts. Through this system, the fan, singer, and label effectively become one working system that operates on a mutual understanding.
