Like the @ Reply and the hashtag the Retweet started with a user named Eric Rice throwing the word "Retweet" in front of a friend's message.
"I honestly don't remember if I had seen it before or how I came to use it," Eric Rice, 41, told ABC News. "The retweet itself was just an off-handed share of a late friend's comment on the state of social media at the time (and was one of the last tweets of his life)."
At the time Rice was working at podcasting company. He has never worked at Twitter and doesn't have plans to buy Twitter stock.
Rice kept using "retweet" in tweets, but according to this post from Mediabistro, the first tweet to use the more popular RT method came from @TDavid on January 25, 2008. In November 2009, Twitter incorporated a retweet feature.
