We take search engines for granted these days. They exist because they have to. Without them, going through and finding relevant information in the millions and millions of pages that exist on the web would be an almost impossible task.

For example, it would have been extremely time-consuming for us here at Pingdom to put together this blog entry if we couldn’t easily search the web for the information we needed.

Above: The big three. Or…?

Here are nine things you probably didn’t know about search engines.

1. Invented in 1936?

The basic idea that would lead to the invention of hypertext and the reasoning behind the need for quick information retrieval of such stored information (the equivalent of today’s search engines) was published way back in 1945 by Vannevar Bush, an American engineer and science administrator. The essay, As We May Think, may have been written as early as 1936. His concept of a “memory extender” device, a memex, contains pioneering thoughts that ultimately led to the creation of the WWW.

2. A magic, automatic retriever of text

The first actual search engine was created in the 1960s by Gerard Salton. He and his team at Cornell University created the “SMART information retrieval system” (SMART stood for Salton’s Magic Automatic Retriever of Text). Gerard Salton is considered the father of modern search technology.

3. First on the internet

The first internet search engine was called Archie, made to index FTP archives. The name Archie is just Archive with the “v” removed.

4. First on the WWW

The first web search engine was called Wandex. It was released in 1993 and used an index created by the first web crawler, World Wide Web Wanderer, written in Perl by Matthew Gray at MIT. Matthew Gray now works at Google.

5. Not much to do

In December of 1993 there were only 623 websites on the internet, which made work for the first web search engines a lot easier than today, when there are more than 162 million websites on the internet.

6. First full text search

WebCrawler was the first search engine that indexed entire pages, and therefore the first to provide full text search like today’s search engines. It launched in 1994. Before then the search engines had only indexed page titles and header information. Today WebCrawler has transformed into a meta search engine, using results from Google, Yahoo, Live search, and others.

7. The Proto-Google

The technology that would become Google was originally called BackRub, a project Larry Page and Sergey Brin started working on in 1996.

8. Yahoo and Microsoft late in the game

Yahoo and Microsoft didn’t have their own search engine technology until 2004. Yahoo Search used data from AltaVista and Inktomi, and was even powered by Google for a while. Microsoft’s MSN Search (now Live Search) followed a similar path (but didn’t use Google) and didn’t launch their own technology until early in 2005 (beta in 2004).

9. The big three – NOT

Google, Yahoo and Microsoft are usually considered the “big three” in search, but this is actually incorrect, at least if you consider the total number of searches world wide. Baidu, the Chinese search engine, surpasses Microsoft’s Live Search in the number of searches made… which would make Google, Yahoo and Baidu the big three.

Do you live in a country that loves Apple’s iPad? Most of us probably think we do, but we wanted to be able to tell you for sure. So even though we have written about the iPad many times before, it’s now time for us to tackle this hotly contested topic again.

Read on to find out, which countries are the most iPad-friendly.

Perhaps you live in one of them.

Display resolutions are increasing every year, something that’s being taken to its extreme with the recent “retina display” trend that came with the latest iPad. The jump in onscreen pixels is massive, and such displays are soon bound to make their way into regular laptops and desktop displays, perhaps as soon as this year.

This development will have a profound effect on the size of the graphics resources necessary for websites, which ultimately will make websites bigger, more bloated and slower to download. That is, if we don’t change tactics.

The juggernaut that is Facebook is quickly approaching 1 billion users, so the social network is growing at a rapid pace overall.

But if we look at some of the latest figures available, it would seem that Zuckerberg’s creation is not gaining users in every corner of the world.

In fact, in one country, Facebook has lost 16% of its users over the last six months, the equivalent of over 200,000 users. But in another country, Facebook has gained almost 17 million users over the same period.

What countries are we talking about, you ask? Read on and we’ll tell you.

Developers who want a portable computer to code on, which is thin, light, sleek and yet powerful, may now be getting another option in an ultrabook from Dell. What makes the “Sputnik” ultrabook different is that it runs Ubuntu 12.04 Linux and it’s tailor-made for developers.

Every Friday we bring you a collection of links to places on the web that we find particularly newsworthy, interesting, entertaining, and topical. We try to focus on some particular area or topic each week, but in general we will cover Internet, web development, networking, performance, security, and other geeky topics.

“Photograph what is close to you. Share it with the world!“ That’s one of the headlines on Aday.org, a global project that will attempt to document what goes around the world in one day.

This all takes place on Tuesday May 15, 2012, and Pingdom will be participating.
