The term octothorpe was coined by engineers at Bell Laboratories in the early 1960s; the scientists at Bell Laboratories modified the telephone keypad and added the # symbol to send instructions to the telephone operating system. Since the # symbol didn’t have a name, the technicians made one up. They knew it should be called “octo-” something because it has eight ends around the edge.
The use of hashtags on Twitter came from a convention used on Internet Relay Chat (IRC). Where the user created channels to discuss a given topic, and each channel was named with a hash followed by a title for the channel – a #hashtag. Chris Messina proposed to adopt the same convention on Twitter so that the user could search for all the tweets talking about the same topic – and the hashtag as we know it now was born!
