introduction of the world wide web
it was the early 90s when brin and page started
working together at stanford, when the internet, or
the world wide web, made its big debut. early
versions of search engines were not easy to use, and
people had to know exactly what they were looking
for before attempting a search. one search could
produce dozens of results that seemed to have no
relevance to what people were looking for. page and
brin felt that there had to be a better way, so they set
to work on a prototype. they ended up writing a
paper called \the anatomy of a large-scale
hypertextual web search engine\ detailing this
prototype. initially, this prototype was called
backrub and was run in page and brins room at
stanford. in 1998, they decided to register it under a
different name outside of stanford, and google was
born.

prototype for their search engine?
