It was first used by Stowe Boyd on 26 August 2007 in his blog post “Hash Tags = Twitter Groupings”.
The # symbol was first used on Twitter by San Francisco based Technologist and Twitter user Chris Messina (@chrismessina) on 23rd August 2007 in a short post which read: ‘how do you feel about using # (pound) for groups.

All they were doing for the next two months was ‘waiting’ for the right disaster to appear, so that they could show their potential to the world.

That event helped to introduce hashtags to a wider audience and proved that disaster is their foundation stone.
