Currently, social media is considered one of the reasons why many Kpop acts are successful. So this got me curious, how did the 2nd generation idols become successful when social media wasn't that much of a thing like it is today? Many new generation idol stans hate it when someone says social media contributes to the success of their favs, something that older idols didn't have so much. How did huge acts like Bigbang, Suju, TVXQ, Snsd, Shinee, Kara etc succeed? Those who were into Kpop then please tell everyone.
