Treated as a four-part company across the catalogue.

Overview
Business model and origins
Rank the web on its own link structure (PageRank) to organize the world's information, then monetize intent at the moment of search with a self-serve ad auction.
Origin
Larry Page and Sergey Brin met as Stanford PhD students; their BackRub research scored pages by who links to them, which became PageRank and then Google. The company nearly stayed a licensing project until Andy Bechtolsheim wrote a $100,000 check to 'Google Inc.' before the entity legally existed. The organic-search breakthrough had no business model for years; Google found it by adapting the pay-per-click search auction GoTo / Overture had pioneered, then compounding it on a data-and-marketplace flywheel.
Hooks from these episodes
Google is profitable enough to build its own data centres, its own servers, and its own undersea cables — which gives it cost advantages competitors can't replicate even with the same architectural decisions.
The four-part Google series treats the company as four businesses, not one.
