Another Thursday night at Facebook...
Another Thursday night at Facebook...
"Dustin, come take a look at this – the graph is crashing."
Sure enough, our active users count was dropping off like a rock shortly before 6pm PST. But I wasn't worried. The same thing happens every week at this time: hundreds of thousands of people tune out of Facebook to tune in to Grey's Anatomy. The dip two weeks ago was actually much sharper than normal, due to a cliffhanger the week before, which enticed more people to start watching on time.
Sure enough, our active users count was dropping off like a rock shortly before 6pm PST. But I wasn't worried. The same thing happens every week at this time: hundreds of thousands of people tune out of Facebook to tune in to Grey's Anatomy. The dip two weeks ago was actually much sharper than normal, due to a cliffhanger the week before, which enticed more people to start watching on time.

This graph shows the number of users logged in through Thursday evening on February 22. 150,000 Facebook users care more about Meredith than their friends.
By the end of the episode, nearly 200,000 people had built up a Facebook craving: the graph comes promptly back up at the end of the hour.

A more granular view of activity: the number of users who have taken an action within a 60 second period. It’s easy to see 10-15k people taking Facebook breaks during each of the commercials. Not Pictured: Another 20k viewers took more traditional bathroom breaks, and 12k made a snack.
At this point, almost ten million different users sign into the site every day, or more than half the user base. During our biggest peaks - Sunday & Monday night around 10EST - more than one million people will be simultaneously logged into the site. So, when something occupies a big portion of the population's attention, we notice.
Dustin, a Facebook co-founder, watches Grey's Anatomy each week solely to keep in touch with Facebook users and definitely not because he's dying to see if McSteamy can handle Addison's bet.
