Hashtags (the # sign attached to the front of a word) have come a long way since they were officially recognized by Twitter in 2009 (they actually originated in 2007.)
Once known only as the “pound” button, the hashtag is now one of the most powerful tools of social media. Hashtags help marketers find what people are talking about within seconds of them posting it.
People create custom hashtags for everything, from movies to weddings. If you don’t know how to use them, learn, because hashtags are here to stay!
