It was a small but negative change to daily active users in Facebook’s most valuable market.
Here’s a troubling data point if you’re a Facebook investor: The company may have finally tapped out its most valuable market, the U.S. and Canada.
Facebook’s daily active user base in the U.S. and Canada fell for the first time ever in the fourth quarter, dropping to 184 million from 185 million in the previous quarter.
It’s a very small decline in a market that Facebook already dominates. But it’s also Facebook’s most valuable market, and any decline in usership — even a small one — isn’t a great sign.
