According to dictionary.com, a hashtag is "a word or phrase preceded by a hash or pound sign (#) and used to identify messages on a specific topic." Hashtags were made popular by Twitter, as the former 140 character limit, was used to make users messages short and sweet. Today, hashtags are used to not only describe the content of the message posted, but it is also used to convey a feeling for example #boring or #imsodone. In a business sense, hashtags are mostly used to find audiences in social media. Whether it's an audience on Facebook, Instagram, or Twitter, hashtags are used to gain a following on these channels.
