YouTube went down because of "technical issues" for an unspecified period this morning (March 25). So calculated the likely impact on the major labels from an outage on the video site.

According to TubeMogul analysis, Vevo videos were getting 14 million views per day through YouTube. Warner Music Group videos received 9.3 million views per day. Throw in a very conservative estimate of 6 million views per day for EMI and that's 29.3 million views per day for the four majors on a global basis.

Assuming all videos are monetized (not a guarantee), and using a rough estimate of 0.65 cents per stream, those 29.3 million views generate about $190,000 per day. Traffic may vary by hour of the day and day of the week, but on average the four majors pull in a combined $8,000 per hour from their YouTube plays.

This calculation is based on total outage. In today's case, it appears embedded YouTube videos were still working, as were videos that were accessed through direct links.

"YouTube is up again following a technical issue which has now been resolved," says a YouTube spokesperson. "We know how important YouTube is for people and apologize for any inconvenience the downtime may have caused."
