You know that a word or phrase has officially made it when it becomes a part of the venerable Oxford English Dictionary. That momentous achievement was announced earlier this summer for “hashtag.” Born in social media, the hashtag has been in existence since 2007 and has skyrocketed in popularity over the past few years. Noted by the # sign in the front of a word, phrase, or string of words, hashtags offer a lot of benefits for users on social media platforms. Many social media sites encourage the use of hashtags, including Twitter (where it all started), Facebook, Google+, and Instagram. They’re not only helpful for users, but savvy brands have leveraged hashtags for marketing purposes as well.
