Crane claims every time a YouTube video turns into a hit, the development takes the form of an “attention spiral”, a geometric pattern that partly follows physical laws. He discovered that a decrease of popularity with certain videos, for example, can be explained through methods usually utilized in modeling the aftershocks of earthquakes. He believes social systems on the web follow the rules of physics and can therefore be analyzed mathematically.

After researching the usage of about 5 million YouTube videos over 8 months, Crane found out that only 10 percent are viewed more than 100 times a day. According to Crane, the popularity of these videos can be measured through distinguishing whether a burst of activity was observed after a large-scale “exogenous” (external) shock or whether it’s the result of a number of smaller “endogeneous” (internal) factors that had a cumulative effect. Also, it seems to be important to take into account the extent to which web users can influence others to take action (what he calls “critical” vs. “subcritical,” where the latter term means exerting influence is impossible).

Crane categorizes especially popular videos into three different classes:

“junk” (exogenous subcritical type, videos that quickly pick up and lose viewers)
“viral” (endogenous critical type, videos spreading through the site through word of mouth)
“quality” (exogenous critical type, videos that attract attention quickly and only slowly lose their appeal over time because of their high quality)

Junk videos are characterized by a significant peak that contains the vast majority of views and fail to spread through the site. In contrast to quality videos, viral videos show precursory growth before peaking out and decaying slowly: It takes time for the endogenous phenomenon to build up and spread within the network. Quality videos, however, reach the peak much faster as a reaction to an external “shock” but also decay slowly.

Crane claims that viral and quality videos show very characteristic patterns over a specific period of time, supposedly making it possible (through the analysis of tendencies) to predict if a video has the potential to become a super hit.

The final goal is the development of an encompassing and science-based online trend monitoring system. The university newsletter writes (German only) Amazon is currently in negotiations with Crane to integrate his model into its site, hoping to predict the potential of newly listed products at an early stage.
