Just what is social media anyway?
Rather than define the term using a bunch of boring jargon that would probably only complicate things further, perhaps best way to get a clearer understanding of it is to break it down into simpler terms.
The "social" part: refers to interacting with other people by sharing information with them and receiving information from them.
The "media" part: refers to an instrument of communication, like the internet (while TV, radio and newspapers are examples of more traditional forms of media).
Okay, so from these two separate terms, we can pull a basic definition together: Social media are web-based communication tools that enable people to interact with each other by both sharing and consuming information.
