The KM Index is based on the Elvis Index which was first introduced by Jon Barger in October 1997. On his homepage
you can find the popularity calculations of over 500 names and objects on 15 October 1997.
All popularity on the Internet is in this method related to the popularity of Elvis Presley.
Since the absolute counts are always changing as the World Wide Web grows, it's necessary to
choose a single reference-point that everything else can be related to. Since 'Elvis' is the
highest-ranking name that's neither religious nor soon-out-of-date, his count on any day
(eg 148.137 pages on January 1st 1998) serves as the 100% marker.
Almost no personal names achieve the rarified strata above Elvis. A single page may currently
be seen as 7.3 micro-elvises (but this figure is always declining as the World Wide Web grows).
Some results:
- God is seven times as popular as Elvis!
- Jesus is three times more popular!
- Microsoft is almost twice as popular as God (and 14 times as popular as Elvis).
- The Beatles are half as popular as Elvis.
- Love is twice as popular as sex (and 14 times as popular as Elvis).
A query on the AltaVista search-engine's "Advanced Search" page makes it possible to get an
exact count of all pages on the World Wide Web containing *any* given word or phrase.
To measure a word or phrase, first get the current figure for 'elvis', then divide that into
the figure for your phrase. Finally multiply this by 100 % to get the percentage (100 % * phrase / elvis).
The number of pages on the internet mentioning 'Knowledge management' is still increasing.

Of course the results are just to be seen as an indication. Not all pages on the Internet are
indexed and not all pages can be indexed since they're inside databases. So AltaVista is always
lagging the net as a whole. Another aspect is the fact that AltaVista used upto May 27th 1998 several
multiple unsynchronised copies of the index. This degree of unsynchronisation causes the index to
be fluctuating. The results therefore change through time. Also has the way AltaVista presents
the counts of pages been changed in October 1998. This caused a 'jump' for the results of November 1998.
Digital claims however on
May 27th 1998 that their new index is truly a global resource.
