Social media existed before smart phones, but smart phones have take social media to new heights. Posting updates and photos from anywhere about anything have become the new norm. Facebook, Twitter, VK, Kik, Whatsapp, Skype, FaceTime, Tinder, Snapchat are all ways people keep in touch via their mobile device.
Because of these, the world has become a much smaller place. People are able to stay in contact with acquaintances and friends from all corners of the globe at all times. In just the click of a button, you can see what everyone you know has been up to. You can get in contact with celebrities. You can get news before it breaks on CNN.
Sharing of art, movies, songs and articles is so much easier with the social apps. You post a screenshot of your phone showing what you're listening to. You check in to whatever movie you're watching at the cinema. You post a picture of your favorite painting.
As social media progresses, I think we can expect these apps to include elements from other apps. Like using FaceTime and Skype to connect with people live on Facebook. Already people like Ricky Gervais and publications like Hot Rod Magazine are streaming live over Facebook for people to watch. It's exciting to think where it will go in the future.
