One of the great things about social media is that is connects people from every corner of the globe. Twitter is one of those social media tools and its hashtag system is used for people for key words or events. An example of a type of hashtag is one during a sporting event, which links fans with sports journalists and announcers together.
The two ways that this is done is both tweeting live updates during a game, while garnering fan reaction in the process, and after the game, when there is analysis about the events that took place. Take this football contest between Ball State University and Northern Illinois University for example. ESPN2 used the hashtag #BALLvsNIU so fans could talk about the goings on in Dekalb, Illinois that Wednesday night.
