It comes as a surprise to some people that the word Internet is always capitalized. Ditto for the abbreviation “Net.” Why is this?
The Internet is like a place. It is a large computer network that connects computers all over the world. In grammatical terms, it is treated as a proper noun. However, as Wikipedia points out, when we refer to the World Wide Web and the Internet, we want to capitalize that, but if we are referring to smaller internet channels, we don’t necessarily have to capitalize them.
By and large, when people write about the Internet, they are referring to the big picture, hence the need for caps. One way to make sure that you spell this right is to perform a spellcheck at the end of your e-mail, article, or manuscript.
It will pick that error up right away.
