 The origin of the Hashtag

A google idea :

Hashtag comes from the verb hash, so you have to hash or classified by using # and a word. The primary function was to classify and list contents in order to find it easily on the web. But after, he proposed to create discussions flow linked to each other by a Hashtag.

A slow launch

This new type of communication did not become viral immediately. Indeed, Twitter waited for 2009 to launch it on its famous social network and allowed people to click on it.

The hashtag’s role evolved on the social network. People no more only classified contents, but they gave a meaning to the content through the hashtag.

The first famous Hashtag was #FF (Follow Friday). People advised others to follow Twitter’s accounts. The hashtag became viral!

In 2013, it arrived on Facebook. Its role was not adapted to Facebook because it helps people to classify short content. However, Facebook offers long content and people can talk to each other through comments. But in 2013, Facebook announced that people will be able to search it and to publish Hashtag on Facebook. Hashtags on LinkedIn will appear the same year as Facebook.
