This edition marks the one-year anniversary of the launch of Billboard's Social 50 chart. While a number of star acts never left the tally (Justin Bieber, Lady Gaga and Rihanna), there have been many viral stars in 2011 with impressive peaks like Pomplamoose (No. 29), George Watsky (No. 13), Rebecca Black (No. 9), Karmin (No. 15) and Kina Grannis (No. 49) that deserve recognition.
After taking home a win at MTV's O Music Awards and releasing her latest music video, YouTube starlet Kina Grannis debuts on Billboard's Social 50 chart. She earned the best Web-born artist O award, and her trippy stop-motion video for "In Your Arms" arrived... full of jellybeans.
