RescueTime, a company that makes tools for businesses eager to understand how they spend their time put together some calculations based on how much time the average user spends on Google versus how much they spent on Google on Friday.
RT took the amount of time its 11,000 users on a regular, PAC-MAN-less Friday and compared it to the amount of time spent on Google on the Friday just gone by. The result? People spent more than half a minute more on Google this past Friday than on any other Friday. RescueTimes users spend, on average about four and a half minutes on Google, so adding an extra 35 seconds doesn't really seem like a big deal.
However, when you consider Google had more than 500,000,000 visitors on Friday (according to Wolfram Alpha), that's an exta 4,819,352 hours spent on Google. Sure, not everyone played PAC-MAN and a lot of those 500,000,000 visitors were probably just there to search and move on, but that number is big enough that even if you say half of everyone on Google on Friday didn't play, that's still nearly 2.5 million hours (2,409,676 if you want to be precise).
RescueTime estimates the dollar tally to be somewhere around the $120 million mark. That's if the average Google user has a cost of $25 per hour (cost being 1.3 – 2.0 X pay rate).
"For that same cost, you could hire all 19,835 google employees, from Larry and Sergey down to their janitors, and get 6 weeks of their time," blogs RescueTime.
