In the beginning the internet was much like a big collection of waste plus useful documents scattered pervasively .Finding information was then , a much breath-halting task .Early search engines were like rudimentary life-forms ,most of them got the basic job done .But as more people desired to connect on the world wide web ,their limitations and dependence on the information that content creators put on so-called meta-tags (strings of text that identified the content of the page in the source code )meant that such engines were liable to be beaten.
Then came the now mega search engine giant Google .What google did was ,it organized the information a lot more better .Instead of depending on the text of the web page to determine the search results ,it determined the page ‘s influence using a variety of factors –like how many times a page has been visited Or linked to.
But there is more to the internet than google and more to search as well .Microsoft’s CEO steve Ballmer had said that five years ago google was just a a small fish in the pan ,as Microsoft readied its (then) latest search engine .Microsoft did not get too far then ,but laid the foundation for an effort that churned out bing ,its search engine launched last year .The engine uses a similar algorithm as google’s page rank algorithm. PageRank is a link analysis algorithm, named after Larry Page,[1] used by the Google Internet search engine that assigns a numerical weighting to each element of a hyperlinked set of documents, such as the World Wide Web, with the purpose of "measuring" its relative importance within the set. The algorithm may be applied to any collection of entities with reciprocal quotations and references. The numerical weight that it assigns to any given element E is also called the PageRank of E and denoted byPR(E).
The name "PageRank" is a trademark of Google, and the PageRank process has been patented (U.S. Patent 6,285,999). However, the patent is assigned to Stanford University and not to Google. Google has exclusive license rights on the patent from Stanford University. The university received 1.8 million shares of Google in exchange for use of the patent; the shares were sold in 2005 for $336 million..
Google founders Larry page and sergey Brin have spoken of their fears of being outsed by a new comer .Google is the laeder in serach but yahoo's Carol Bartz is looking to catch up .
