"Billboard and Nielsen announced today the addition of U.S. YouTube video streaming data to its platforms, which includes an update to the methodology for the Billboard Hot 100, the preeminent singles chart.
"The YouTube streaming data is now factored into the chart's ranking, enhancing a formula that includes Nielsen's digital download track sales and physical singles sales; as well as terrestrial radio airplay, on-demand audio streaming, and online radio streaming, also tracked by Nielsen.
"Billboard is now incorporating all official videos on YouTube captured by Nielsen's streaming measurement, including Vevo on YouTube, and user-generated clips that utilize authorized audio into the Hot 100 and the Hot 100 formula-based genre charts – Hot Country Songs, Hot R&B/Hip-Hop Songs, R&B Songs, Rap Songs, Hot Latin Songs, Hot Rock Songs and Dance/Electronic Songs – to further reflect the divergent platforms for music consumption in today's world.
"The most notable YouTube-influenced title this week is viral sensation 'Harlem Shake' by producer Baauer, which debuts at No. 1 on both the Hot 100 and Streaming Songs charts and jumps 12-1 on Dance/Electronic Songs with 103 million views, according to YouTube. According to Nielsen, the "Harlem Shake" arrival also benefits from viral video-influenced sales of 262,000 downloads. That sales sum alone, good for a No. 3 ranking on Hot Digital Songs, would have placed the track within the top 15 on the Hot 100 without the inclusion of YouTube streams into the calculation" (http://www.billboard.com/articles/news/1549399/hot-100-news-billboard-and-nielsen-add-youtube-video-streaming-to-platforms, accessed 02-21-2013).
