Questions are being asked about the web giant’s waning powers, but it may just be a storm in an online teacup
For seasoned users of the internet, the chronology of our era divides into two ages: BG and AG – before and after Google. The year 1998 marks the dividing line. Before then, as the web expanded exponentially, a host of “search engines” had attempted to provide searchable indexes to it. The best of them was AltaVista, which launched in 1995 and provided the first searchable, full-text database of the web via a simple interface. It was the engine that I and most of my colleagues used until one fateful day in 1998 when an even starker webpage appeared with a simple text box and almost nothing else except the name Google. And from the moment you first used it, there was no going back.
Why? Because Google used an original way of ranking the relevance of the results turned up by a query. It effectively conducted an automated peer review of websites. The more webpages linked to a particular site, the more relevant it was likely to be and so it was given a higher ranking. The algorithm, dubbed PageRank, which did this was the foundation on which Google’s domination of the internet search was built.
