Social media was bigger than ever in 2015, and not always for the better.
Just like everyone else, Hollywood stars used social media to speak their minds. But unlike the average user, they had millions of followers reading what they wrote. Whether their social media rants changed things for the better or were simply full of hot air, they were nevertheless fun to follow.
From Taylor Swift's game-changing letter to Apple Music, to Donald Trump's endless stream of angry tweets, see the 11 best social media rants of 2015 below.
1. Taylor Swift vs. Apple Music
Pop megastar Taylor Swift single-handedly changed the music industry when her open letter to Apple convinced the company to reconsider its policy of not paying artists streaming revenue for music streamed during the free trial period.
"It's not too late to change this policy and change the minds of those in the music industry who will be deeply and gravely affected by this," she wrote. The company reversed its policy later that same day.
2. Nicki Minaj vs. VMAs/Taylor Swift
When Nicki Minaj's "Anaconda" music video was snubbed by the MTV Video Music Awards for Video of the Year, the rapper didn't hold back her criticism on Twitter, accusing the show of body shaming and racism, and of favoring videos by thin, white artists. Taylor Swift took the tweets as a personal attack, launching pop music's biggest feud of 2015.
3. Stephen Amell vs. Stereotyping Texas
You don't mess with Texas, at least not if Stephen Amell has anything to say about it. The "Arrow" star came to the state's defense when he felt like it was getting a bad rap following the case of a 14-year-old Muslim boy who was unfairly arrested over a science project. The subsequent backlash was so intense, it drove Amell to take a hiatus from social media.
4. Zendaya vs. Giuliana Rancic
It was the borderline-racist joke heard around the world. When Giuliana Rancic made fun of Zendaya's Oscar dreadlocks on E!'s "Fashion Police," the Disney star came back with an Instagram post putting her in her place. The kerfuffle that followed resulted in the departure of Rancic, as well as co-hosts Kelly Osbourne and Kathy Griffin.
