Spelling

The lowercase form internet is now widely favored over the capitalized spelling Internet. Originally, the word was capitalized as a proper noun to distinguish the network that we now know (having developed from the large and specific U.S. Department of Defense ARPANET network) from smaller, more generic linked networks. Two major trends have eroded the former use of the capitalized form: the growing perception of the internet as a generic entity, and the general trend toward lowercase spelling and other shortcuts that minimize keystrokes in digital communication. Accordingly, the lowercase form internet was first embraced in digital media and informal writing. It was subsequently adopted by technology-related publications. Major newspapers and style guides have also now adopted the lowercase form internet as standard. The capitalized spelling may still be found in older published material or in some linguistically conservative publications. However, while either form is acceptable in writing (as long as it is used consistently), the lowercase spelling internet is the form best adapted to its evolving use.

Explanation

The internet is a huge computer network made up of smaller computer networks. You're on the internet right now! When you visit a website for news, videos, social networking, email — or even this definition — you’re on the internet. The internet — which is usually, though not always, capitalized — connects computers, allowing you to send and receive information. Facebook, Twitter, YouTube, email, and many other forms of communication could not exist without the internet, which uses TCP/IP network protocols. People get on the internet using computers, smartphones, and other electronic devices. The Internet is also called cyberspace and the net.
