YouTubers, sometimes called YouTube personalities or YouTube celebrities, are a class of Internet celebrity and videographers who have gained popularity from their videos on the video-sharing website, YouTube. Some YouTube personalities have corporate sponsors who pay for product placement in their clips or production of online ads. Networks sometimes support YouTube celebrities.
YouTubers have become an important source of information and entertainment for the Millennials-generation. In an 2014 survey conducted by the University of Southern California among 13-18 year-olds in the United States on whether 10 YouTube celebrities or 10 traditional celebrities were more influential, YouTube personalities took the first five spots of the ranking, with Smosh ranking as most influential. When repeated in 2015, the survey found six YouTubers on the first ranks, with KSI ranked as most influential. YouTubers are seen as more relatable and authentic, fostered by the direct connection between artist and viewer using the medium of YouTube.
