A decade ago, social mediaâthat is, social network sites like MySpace and Facebookâwere taking off among teens and fan communities. News consumption in the US was shifting as well, as cable news outstripped network shows and print circulation declined.

Planned changes to the Facebook News Feed algorithm cultivated this process further. By 2015, breaking events like theÂ Charlie HebdoÂ shooting in Paris unfolded online in a new way, sparking the #JeSuisCharlie hashtag and public memorials across Europe hours later.
