What is Social media?

[Abbzug]

It's published person-to-person communication that's available to a mass audience. Published content that can be produced or edited by anyone can also fall into this category. "Social media" generally implies some relation to the internet but pirate or HAM radio broadcasting, public-access channels, and probably some other media can be considered social media as well.

"Social media" isn't a broadly-used term. You could probably be a dink and argue that all media are inherently social if you really wanted to.
