In 2012, South Korean artist Psy released 'Gangnam Style,' a K-pop track that would fundamentally change the digital music landscape. The song's music video, featuring the iconic 'horse dance,' became the first video in history to reach one billion views on YouTube. Its popularity was so immense that it forced YouTube to upgrade its view counter from a 32-bit integer to a 64-bit integer because the view count exceeded the previous maximum of 2,147,483,647. Despite the lyrics being primarily in Korean, the song's catchy hook and humorous visuals led it to the top of the charts in over 30 countries. It served as a major catalyst for the 'Hallyu' (Korean Wave), introducing a global audience to K-pop and proving that non-English tracks could dominate the social media era. Psy's success opened doors for future K-pop acts like BTS and Blackpink on the global stage.
