From the article:

- 75 billion revenue total

- 52 billion "AdWords and Search Advertising"

- 15 billion AdSense

So yes - the vast majority came from the ad business:

15+52=67 billion (90%) from the ad business, that leaves just 8 billion from all other businesses.

"came from Google’s own websites" - that was traffic, it still was ad revenue! With that ad revenue they created free content websites like Youtube. But what pays for Youtube are Google's ads. It is ad revenue. Creating a huge free video site over the years when you have billions to subsidize it is not a sign of superior business intelligence in my opinion.

I never disagreed with that. Originally you said:

> Or do they? The vast majority of their income still is from the search business alone.

This is very different, their search business is a subset of their add business.
