Techopedia explains Netiquette
This term was first introduced in posts of the satirical “Dear Emily” news columns in 1983, but it originated before the World Wide Web. In that era, the commercial use of public posting was not popular and internet traffic was dominated by text-based emails, Gopher, Telnet and FTP from educational and research authorities.
Although the specific rules governing netiquette may be different depending on the forum being used, it is equally applicable to chatting, blogging, message boards, email and surfing the Internet.
