History of Search Engines
When the World
Wide Web came into being in the early 1990s, almost twenty years since the
‘ARPANET’ went public, it has thrown open the doors to a virtual and vast
new world of information, which was both unfathomable and ever expanding.
But, as the number of web pages and the number of people accessing the
internet increased, accessing a particular resource from the sea of
information became a problem, especially in the event of the person not
knowing the URL of a particular website. Necessity has always been the
mother of invention; the need for a tool to search the required resource
from the millions of pages of information in the World Wide Web was gravely
felt and the researches for the same culminated in what is now called the
first amongst the first generation search engines, ‘Archie’.
‘Archie’ –
created by Alan Emtage in 1990 – used the directory listings of all files
existing in the public anonymous FTP websites to create a searchable
database of file names. A year later, Gopher, which does the similar purpose
of Archie, but with text files, was introduced by Mark McCahill at the
University of Minnesota. The programs, ‘Veronica’ and ‘Jughead’, which
followed Gopher, worked similarly, on plain text files sent via Gopher.
The world of
web search took a decisive turn in 1993, when the MIT student Matthew Gray
made the first robot, the World Wide Web Wanderer. It was initially
meant to count web servers in the World Wide Web, but was later reprogrammed
to search URLs as well, thus forming the first website database, Wandex.
ALIWEB released in 1993 was also a robot, but with an added feature allowing
users to submit their own URLs for indexing purposes.
Web robots are
also called web crawlers, web spiders or web wanderers. In its earlier
versions, it was criticized for taking too much bandwidth, often leading to
a server crash. But the issue was sorted out in the later generations.
As the World
Wide Web started to grow phenomenally by the mid 90s, realizing its
financial potential, more players began throwing their hats in the ring.
Excite was the first to make their presence felt and it used statistical
analysis of word relations to spot a particular web resource. It was
followed by Yahoo in 1994, as a website providing a listing of its favorite
web pages. The format of the main link or URL followed by a brief
description of what is in the site was first introduced by Yahoo. Within a
year, funds started to flow in, and soon Yahoo became a corporation.
Lycos, with its
prefix matching, relevance retrieval, and word proximity, announced its
entry in almost the same period as Yahoo. It was a large search engine and
by 1996, it had indexed over 60 million web pages, the biggest by any search
engine of that time. Alta Vista is another search tool that had made
headlines – again in the same period - with advanced search options and
allowing natural language inquires. It was also the first to provide
multimedia search options to find music files, videos, and pictures.
Irony it may
be, the search engine that is touted as the most popular today – the Google
– came into existence rather late in the scene, in 1997. It used inbound
links to rank websites, but the results it produced were hugely accepted and
in another one year’s time, it became the most sought after search engine in
the world. Its nearest competitor, MSN Search, and Open Directory – the
biggest hand edited catalogue of the web – came into being in 1998.
As of now,
Google has the most number of patrons, followed by Yahoo and MSN.
This wind up a
brief peep into history of search engines…
In the near
future, as the scene consolidates, the number of search engines that remains
in the race may come down to the current top few. But, then all will be
providing more advanced and diverse features alongside searching, and it is
the common netizens who is stand to gain from the final outcome. After all,
this is how product economics responds to competition!
Tail Piece: The
numbers of search engines that came and vanished without leaving a trace in
between are many. But only the important ones have been mentioned in the
article.
