From the Publisher
Stop! Take a look around.
You’re surrounded by inventions that make your life safer, easier, more exciting, informing, and entertaining.
Your home is packed with life-enhancing innovations, from central heating and flushing toilets, to TVs with hundreds of channels. Outside, you can travel fast in cars, buses, or trains, while jet airliners roar overhead, transporting people all around the planet. Digital devices such as smartphones and tablets let you communicate with anyone, anywhere in the world, and if you get injured or ill, high-tech hospitals are packed with inventions to make you better.
But things weren’t always this way, so how did we get here? This book is your time-traveling guide. It runs backward, starting at the end and ending at the beginning. You will venture further and further into history, to a time before each invention existed.
Get ready, turn the page, and head back in time…
LIFE BEFORE…The World Wide Web
Before the World Wide Web, information was only at your fingertips if you had the right book in your hands!
If your parents or home bookshelf couldn’t answer your question, it was off to the library. Your search for answers could take time as you combed through lots of books, magazines, or newspapers. Although your family might have an early home computer, there were no websites or search engines. Researchers, journalists, and other information workers often spent days in specialized libraries hunting down key facts.
INVENTOR: TIM BERNERS-LEE (b. 1955)
In 1980, British programmer Tim Berners-Lee wrote ENQUIRE, a program to keep track of people and projects at a science center in Switzerland. Berners-Lee’s program used links between pieces of information called hyperlinks. Clicking on a hyperlink sent you to another piece of information. In 1989–90, he developed a global version of ENQUIRE called the World Wide Web. The first website was available from August 1991.
WEBSITES
A website is a collection of documents that are stored on a computer, called a web server. Each page of a website (a webpage) has its own unique address called a URL. All webpages are marked up using a special language called HTML, which allows them to be accessed via the Internet by any computer.
INFORMATION BOOM
The World Wide Web began slowly. By June 1993, there were only 130 websites in the world. As more and more people gained Internet access, website numbers soared to 17 million by 1999 and more than 800 million today. Many websites, including newspapers and encyclopedias, contain vast amounts of useful information only previously available on paper.
