More chart illiteracy probably. Here's a chart zoomed in https://trends.google.com/trends/explore?date=2016-09-01%202... and the fake news area under the curve is quite a bit larger until around the time of the election. About the most honest thing you can actually say is that around the election people just started googling it more. Big whoop. There isn't any correlation with the term "fake news" as you may glean from the first chart.
