Billboard + Twitter = Real-Time Charts
Billboard has teamed up with Twitter to launch their first “real-time” foray into defining what artists are ruling the charts.
The first of the real-time charts, the Billboard Trending 140, is an up to the minute ranking of songs shared in the U.S., measured by acceleration over the past hour. This chart can be filtered to present a real-time view of the most shared track in the U.S. over the past 24 hours, with a weekly summary presented as the Billboard Twitter Top Tracks chart on Billboard.com and in print in Billboard.
They’ve published an FAQ if you’re into that sorta thing.
