Wiz Khalifa video hits 1 billion YouTube views

Wiz Khalifa and his video "See You Again" hit a milestone this week, becoming the tenth video ever to cross 1 billion views on YouTube.

At 184 days, "See You Again" is the second-fastest video to hit 1 billion in YouTube history (after “Gangnam Style”), and the quickest of the past year.

Khalifa and Charlie Puth’s tribute to the late Paul Walker joins what appears to be an ever-accelerating trend in billion-view videos.

Released in April of this year, it is the first ever rap / hip-hop video to reach one billion views on YouTube.

For ten years, the Billion View Club was one of the most exclusive circles on YouTube, but in 2015, things changed. At the start of this past June, only two videos had reached that echelon. But in just the past six months, EIGHT additional videos crossed the mark. Here are the videos ranked by views with a graph showing the trajectory of these videos over the past five years.
