Apps whose downloads were advertised to the Facebook residents gained bit by bit in popularity, and rates had no clear connection to amicable pressures.
But at a particular recognition threshold, rounded off the same opposite a far-reaching operation of apps, downloads began to skyrocket.
The authors of the research in PNAS say that in the offline world, no such "switch" is well known to exist.
The information were collected in mid-2007, when the site had 2,720 apps and 50 million users.
At that time, a Facebook user's apps were all manifest to their friends, and the friends were told when a new app was downloaded; Facebook has given stopped the practice.
In research led by Oxford University, Jukka-Pekka Onnela and Felix Reed-Tsochas carefully thought about anonymised information about the downloading of all the apps over a 50-day period.
They found that what they tenure "social influence" plays a purpose usually for a few of the apps on a given day.
"The startling anticipating is that two qualitatively not similar behavioural patterns emerged," Dr Onnela told BBC News.
"There appeared to be a limit of popularity, and users usually seemed to be shabby by the choices of others for apps fibbing on top of this threshold.
Dr Onnela mentioned the engaging thing about the information is that the millions of users were beneath no outmost influence, with the poise outset casually as people done eccentric choices formed on the clear choices of their friends and other Facebook users.
"Social change is strongly present in online informative expenditure but, at least in this case, usually for a subset of products," he said.
It waste to be seen if a similar limit poise occurs in non-social network or truly entirely offline contexts. Dr Onnela mentioned that the burden would be in replicating the rarefied conditions of a hands-off investigate of millions of "cultural consumers".
"Most 'real-world' studies concentration usually on the many rampant products and behaviours," he explained.
"Had you done the same in our study, you would have usually celebrated one behavioural pattern, not two."
"It is without skepticism a really large study," mentioned Bernardo Huberman, a assistant professor for HP Labs whose new work has shown the offline belongings of tweets on the success of films.
"As to its conclusion, it reminds me of the 'tipping-point'-type transitions discussed by many amicable psychologists and popularised by Malcolm Gladwell," he told BBC News.
He points out that the paper moreover demonstrates a anticipating reflecting his own work, namely that the "present recognition of an piece presaging its future popularity", mirroring his own work and, more recently, that of Yahoo researchers.
