Twitter Turns 10: Looking Back at How the Music Industry Started Tweeting

Ten years after Jack Dorsey wrote that he was "just setting up my twttr," fewer people are doing just that. In February, the company reported flat growth spanning recent quarters — hovering around 320 million monthly active users -- and it recently spiked the idea of killing the 140-character limit after public outcry. Turning 10 hasn’t inspired a significant spike in it stock price, either.

But hey, when it’s your birthday you’re allowed to kick back and forget all your worries right? Right? So on its 10th birthday, Twitter is spending the day thanking its dedicated users around the globe. "Throughout the years, you’ve made Twitter what it is today and you’re shaping what it will be in the future," the site wrote on its blog. "Thank you for making history, driving change, lifting each other up and laughing together every day."

Many of those history-making moments and milestones included celebrities and music stars, like Ellen DeGeneres’ selfie from the 2014 Oscars, which is still the most retweeted tweet ever with 3.3 million to date. The most followed person? Katy Perry, with her 85 million followers. The world’s most mentioned person? Justin Bieber.

To mark the occasion, we thought it would be fun find out what many of the biggest players in the music business had to say in their first tweets. Some are embarrassing, others give shout-outs to Ashton Kutcher (the first to 1 million followers — remember how big of a deal that was?), and others just wanted to let you know they were watching HBO.
