The social network points to the Osama bin Laden raid and the "pro-democracy movement in Egypt" as some of the top stories that impacted Twitter this year.
As 2011 comes to a close, Twitter has decided to take a look back at some of the big stories that impacted tweeters around the globe in a new series, called Year In Stories.
One of the stories Twitter highlights is Shohaib Athar's sudden rise to fame. While he was sleeping in bed earlier this year, he heard a helicopter overhead, saw what was going on, and took to Twitter to tell followers what was happening. What Athar didn't know at the time was that he was live-tweeting the raid on Osama bin Laden's compound, and he was the first person in the world to report on the events of that day.
Twitter also played an integral role in what became the Arab Spring. Not only did the social network prove to be a place for concerned people to get the word out and show support, but in January, Wael Ghonim, an Egyptian man and Google's head of marketing for the Middle East and North Africa, did much more than that when he tweeted, "I said one year ago that the Internet will change the political scene in Egypt and some friends made fun of me." A day later, he was detained for organizing protests against the government. Although he was eventually released, his arrest played a key role in the Mubarak government's downfall.
But Twitter didn't stop there. Here are some of the other stories Twitter says its service helped write this year:
Twitter's Year In Stories is the first of what will be several lists coming from the company this month, including its top tweets, trends, and hashtags.
