They certainly overlap, which is why it gets confusing. For example, you can share media with your social network to gather likes and comments — a form of social networking. But you can also just upvote a link on Reddit, which is a social media platform, to help out the community and give your say in the matter without any intention of building relationships with other users. 
Another thing to consider is that the most commonly-shared content on social media is an image. So, always include an image with your posts. This will dramatically increase your chances that one of your followers will share the post with their network. While building up a large network of followers is great, ultimately what you want is to have your followers—no matter how many you have—share what you're posting with their network, and those people will share your post with their followers, and so on.

Networks formed through social media change the way groups of people interact and communicate. They "introduce substantial and pervasive changes to communication between organizations, communities, and individuals."[1] These changes are the focus of the emerging fields of technoself studies. Social media differ from paper-based media (e.g., magazines and newspapers) and traditional electronic media such as TV broadcasting in many ways, including quality,[5] reach, frequency, interactivity, usability, immediacy, and performance. Social media outlets operate in a dialogic transmission system (many sources to many receivers).[6] This is in contrast to traditional media which operates under a monologic transmission model (one source to many receivers), such as a newspaper which is delivered to many subscribers, or a radio station which broadcasts the same programs to an entire city. Some of the most popular social media websites are Facebook (and its associated Facebook Messenger), Instagram, WhatsApp, Google+, Myspace, LinkedIn, Pinterest, Snapchat, Tumblr, Twitter, Viber, VK, WeChat, Weibo, Baidu Tieba, and Wikia. These social media websites have more than 100,000,000 registered users.
