What is a hashtag?

Last Updated: Jul 20, 2015 11:25AM PDT
A hashtag is any word in the social conversation that begins with the '#' symbol.  Americans refer to it as a 'pound sign', but it's known as a 'hash' pretty much everywhere else.  A '#' in front of a word like 'politics' makes it a hashtag:  #politics!

What are they used for?  If you haven't noticed, hashtags are everywhere!  Politicians have them (#Obama), sports leagues use them (#Superbowl, #NBA), & television shows like "American Idol" (#idol) have them, too.  Hashtags simply let you associate your tweets with a larger topic, group, or conversation.  It's like adding keywords to your message to make it globally searchable, driving social reach and inspiring conversation.
