What types of information systems are involved with social media?

[Selena]

I am writing a report on social media and come up with answers to the questions
"What types of information systems are involved?"
What would be some examples of information systems involved with social media?
Thank you so much.

A definition might be useful (from Britannica Online):
Information system, an integrated set of components for collecting, storing, and processing data and for delivering information, knowledge, and digital products. (...) Digital goods, such as electronic books and software, and online services, such as auctions and social networking, are delivered with information systems. Individuals rely on information systems, generally Internet-based, for conducting much of their personal lives: for socializing, study, shopping, banking, and entertainment.

So... Essentially, anything that gives you the option to log on with your Facebook account, Reddit account, Twitter account or so on, will be "involved with" social media. This will obviously include any portable device that gives access to one or more of the same services, for instance any tablet, smartphone, and so on.
