A lot can happen in a year. From Spring 2013 to now, the most important social platform to U.S. teens has shifted from Facebook to Twitter and then to Instagram according to a report from PiperJaffray. Facebook’s importance to teens has declined by nearly half. Twitter seems to have experienced a brief rise in importance relative to other social networks before falling back to its original level.

Perhaps the most important thing to note is what this chart does not show. That from this relatively short period of time, what teens consider to be the most important of social networks is moving away from these top 3. Instagram may be the current title holder, but its prominence isn’t what Facebook’s was a year ago while Twitter isn’t keeping up.

Facebook’s preciptous fall in favor may be part of a larger trend of teens diversifying social platforms with gusto. The chart doesn’t show SnapChat, Tumblr, Pinterest or a number of other networks popular with this age group. Perhaps within the next year, we’ll be seeing a new network or two make their way into this graphic.
