social media in my opinion has indeed evolved over the years. Social media prior to Facebook was not as widely available to most people. Once Facebook launched in 2004. It opened the door to many people making their opinions available to others. It allowed for others to connect with others in order to strengthen the social networking community. Allowed also is a good social networking avenue allowing other people to connect with others via vlogs and videos and also to create a fanbase for their youtube channels. I do not not tknow much about instagram but I would imagine it is similar to flkr allowing users to post pictures of themselves and their daily environments. Twitter is another neart site that I believe will overtake facebook as far as popularity becuase it is growing a younger fanbase of followers where as facebook is more appealing to people in middle age years.
