The World Wide Web was invented by Sir Timothy John Berners-Lee, British scientist, during his time at CERN

The first website at CERN – and in the world – was dedicated to the World Wide Web project itself and was hosted on Berners-Lee’s NeXT computer. In 2013, CERN launched a project to restore this first ever website:

Did you know:
Everything that makes up the Web runs over the Internet, but there is a lot more to the Internet than the Web.
The Internet provides the foundation for all kinds of applications, like email, chat, and video conferencing—and also the Web.
Every time you message someone on WhatsApp, iMessage or Facebook Messenger, you are using the Internet, but NOT the Web.
The same is true of Telegram, Signal, Viber, and most other messaging systems.
NOTE: the messaging systems may have a web interface where you can read and compose messages, but they also have non-Web clients (ex. apps) and when they are sending/receiving messages, they are doing so using non-Web protocols.
Every time you make a video call over Skype, Facetime, Zoom, WhatsApp, you are using the Internet, but NOT the Web.
Every time you send or receive an email message, you are using the Internet, but NOT the Web.
(Note that you might be using a Web interface to read or write the email, but the actual sending and receiving takes place using non-Web protocols.)
When you are playing online games using apps you install on your computer, you are using the Internet, and probably not the Web.
When you use apps on your mobile phone, those are using the Internet – and may or may not be using the Web.
(Some apps on your mobile phone are written natively for Android or iOS and use protocols that are NOT for the Web – but in many other cases, what you see as “apps” are basically small, separate web browsers that then pull up a website inside of the “app”… so it is a Web site, traveling over the Internet, that is then viewed inside of an “app” on your mobile phone.)
When you store files on DropBox, Box.com, Microsoft OneDrive, etc., you are using the Internet – and you *might* be using the Web if you are using the Web interface to upload files – but if you are using the native integration into Windows or Mac OS X, those are not using the Web.
When you use group calendaring tools, many of those use non-Web protocols – again, you are using the Internet, but not necessarily the Web.
The Web would not exist without the Internet … but similarly the Internet would not have grown into the amazing and powerful tool it is without the Web.
The Web needs the Internet to work… but the Internet needs the Web to be useful.
The Web relies on the Internet to get content to people … and the Internet relies on the Web for the content people want.
“While the Web is probably the largest service on the Internet that most people use, it’s not all of the Internet,” stated Andrew Sullivan, CEO of Internet Society. “In fact, the Web would not exist without the Internet … but similarly the Internet would not have grown into the amazing and powerful tool it is without the Web.” “It’s the open architecture of the Internet that makes the wonders of the Web possible,” added Sullivan.
