4. Slide 4: I What About Google?
5. Slide 5: I.1 Google history • Back in 1994, in Stanford, two friends, one finalists project ... and one Idea!
6. Slide 6: I.2 Google history Consider an internet page. I know where it links to ... but ... I don’t know where it’s linked from. Larry’s one-billion dollar pop quiz: Which pages link to this page?
7. Slide 7: I.3 Google history A year later BackRub was born. Innovative, this program would send crawlers to slurp the pages in the integral and then it would index their links, thus providing for the first time a snapshot of the links structure of the internet. A natural ranking of web pages followed. They called it the PageRank, from the name of its creator, Larry Page.
8. Slide 8: I.4 Google history With the index and the PageRank concept they pushed their data to the next level and created a novel search engine: i – It allowed full-text search ii – It ranked its results according to the PageRank principle They named it Google, after a typo when trying to write googol (10100).

Slide 9: I.5 Google history With the index and the PageRank concept they pushed their data to the next level and created a novel search engine: i – It allowed full-text search ii – It ranked its results according to the PageRank principle They named it Google, after a typo when trying to write googol (10100). Their moto is: “Don’t Be Evil!”
