The Web Is Shrinking

[Commentary] Online video is exploding, with annual user growth of more than 45 percent. Mobile-device time spent increased 28 percent last year — with average smartphone time spent doubling. And social networks are now used by 90 percent of U.S. Internet users — for an average of more than four hours a month.

But what’s happening to the rest of the Web? . Really.

When you exclude just Facebook from the rest of the Web, consumption in terms of minutes of use shrank by nearly nine percent between March 2010 and March 2011, according to data from comScore. And, even when you include Facebook usage, total non-mobile Internet consumption still dropped three percent over the same period. We've known that social is growing lightning fast — notably, Facebook consumption, which grew by 69 percent — but now it’s clear that Facebook is not growing in addition to the Web. Rather, it’s actually taking consumption away from the publishers who compete on the rest of the Web. In the last year, Facebook’s share of users’ time online grew from one out of every 13 minutes of use nationwide, to one out of every eight. In aggregate, that means the document Web was down more than half a billion hours of use (that’s more than 800 lifetimes) this March versus last March. And in financial terms, that represents a lost opportunity of $2.2 billion in advertising inventory that didn't exist this year.
