On February 20, 2013, "Billboard" announced another change in the methodology for its charts that incorporated YouTube video streaming data into the determination of ranking positions on streaming charts. The incorporation of YouTube streaming data enhanced a formula that includes on-demand audio streaming and online radio streaming. The YouTube video streams that used in this methodology are official video streams, Vevo on YouTube streams, and user-generated clips that use authorized audio. "Billboard" said this change was made to further reflect the divergent platforms of music consumption in today's world.
