Remembering the 2010s

Hard to believe that this decade is coming to an end; it seems like yesterday that we were saying hello to 2010, and here we are, saying goodbye to 2019. Yes, the 2010s are over, but not over yet are the series of trends they left to us, cultural phenomena, events that made a singular difference on the field of entertainment. Let's call them 'era-defining events' for lack of a better word.

For which of these 'events/trends' will you most remember the 2010s or do you think the 2010s should be most remembered for?
