Twitter’s First Hashtag Was Posted 8 Years Ago



HashtagHave you ever wondered why people started using hashtags on Twitter? Today, it’s not unheard of for a group of people, who are all tweeting about the same event, to use three or more hashtags to describe it. We may have reached #hashtag #overload.

Eight years ago, that wasn’t so. The very first person to suggest that people who are all tweeting about the same thing use a # (pound) was Chris Messina. His very influential tweet was posted on August 23, 2007.

Who is Chris Messina? His bio says: “I invented the hashtag, advocated for many open source and open web projects, and co-founded BarCamp and coworking communities. I previously worked at Google in developer relations as a UX designer.”

It’s pretty amazing to see how far his suggestion to use what was then refereed to as a pound symbol has gone. Why did he choose the pound symbol, instead of some other one?

In another of his tweets, Chris Messina notes that Twitter (the company, not the users) resisted using hashtags in the beginning. He points out that hashtags were not intended to be Twitter-only. Today, we see them on Twitter, Facebook, Instagram, and Tumblr.
