Since 2010, Twitter has logged popular hashtags, tweets and users, but this year, the service explored influential discussion topics. Hashtags created months apart after separate terror attacks in Paris, #JeSuisCharlie and #PrayforParis, gave people around the world a chance to collectively express their sorrow. (And gave others an opportunity to market memorabilia.)
Twitter, a service that logs about 320 million active users monthly, says that 79 percent of those accounts are from outside of the United States. Still, topics of particular interest to Americans dominated the list. Using several influential hashtags, people expressed their opinions about social justice at a time when the country was openly grappling with civil rights, discrimination and racism. #LoveWins, a hashtag that sprang up after the United States Supreme Court guaranteed the rights of same-sex couples to marry, cataloged widespread celebrations.

Another hashtag, #IStandWithAhmed, was created around one the biggest social stories of the year. A global outcry emerged after 14-year-old Ahmed Mohamed was detained by the police for taking a homemade alarm clock to school in Irving, Tex. Ahmed saw such widespread support on social media that President Obama invited him to a White House event. He has since moved with his family to Qatar.
#BlackLivesMatter, a social media movement that developed as people protested the deaths of black men by police officers, became an avenue for protesters to congregate both online and in person. (Protests in Ferguson, Mo., were highlighted in Twitterâs 2014 report.)

Individuals made great strides on the platform. After unveiling her Vanity Fair cover, Caitlyn Jennerâs Twitter account reached 1 million followers faster than any other. She has since used her platform on social media as a way to speak out about issues facing transgender people.
Aside from the attacks in Paris, Europeâs refugee crisis resonated globally, as did elections in Canada, Singapore and India. The most-retweeted honor belonged to members of the English boy band One Direction. A message from Harry Styles after his bandmate left the group took the top spot that Ellen DeGeneres snagged at the Oscars last year.
(A tweet from the departed bandmate, Zayn Malik, made second place.)
