FYI facts for kids

"FYI" is a common and handy abbreviation that stands for "for your information". People use it a lot in messages, especially when they want to share something helpful or interesting without asking for a reply or expecting someone to do anything.

You'll often see "FYI" in emails, text messages, and even hear it in everyday conversations. It's a quick way to say, "Hey, here's something you might want to know!"

The History of FYI

The term "FYI" has been around for a long time, since at least 1915! It first became popular with journalists who used wire services to send news. Back then, every word in a telegraph message cost money. So, using a short abbreviation like "FYI" was a smart way to save space and money while still getting the message across.

FYI in the Internet World

When the Internet started to grow, "FYI" found a new and important role. It became part of a special series of documents called Request for Comments (RFCs), which are like official guides for how the Internet works.

The "FYI" series of notes was created to be a central place for people to find all sorts of information about the Internet. These documents can explain anything from why certain things were designed the way they were (like a "Why it was done that way" memo) to answers for common questions about how to use the Internet. They help everyone understand the Internet better.
