It is 10 years since the hashtag was first used on Twitter in what was a fairly mundane comment that would revolutionize the use of this now popular digital symbol.
It was former Google and Uber engineer Chris Messina who came with the idea of using “#” as a way of tagging or categorizing a tweet on Aug. 23, 2007.
That tweet that would change everything simply read: “How do you feel about using # (pound) for groups. As in #barcamp [msg]?”
