extranet

A private network that uses Internet protocols, network connectivity, and possibly the public telecommunication system to securely share part of a business's information or operations with suppliers, vendors, partners, customers or other businesses. It can be viewed as part of a company's Intranet that is extended to users outside the company (eg: normally over the Internet). It has also been described as a "state of mind" in which the Internet is perceived as a way to do business with other companies as well as to sell products to customers.

extranet meme

(Or outernet meme) A meme that gained popularity by distribution outside the internet.

The word "extranet" is a retronym - a word used to describe an object or entity that has been superseded by a new kind of thing, where the original object or entity was not previously described using the new word.

Examples: email and snail mail (snail mail being the retronym for ordinary "mail"); quantum mechanics and classical mechanics (before the discovery of quantum mechanics the way matter interacts on the superatomic scale was simply "mechanics"); and finally, internet meme and extranet meme.

Examples of popular extranet memes:

Keep Calm and Carry On

Pretty much any idea that became widespread without using the Internet.
