Over the 12 months ended in September, Google’s ad business accounted for 89 percent of Alphabet’s revenue, or $76.1 billion. As one ex-executive puts it, “No one wants to face the reality that this is an advertising company with a bunch of hobbies.”Wow - that's a lot of money from clicks and YouTube ads. (Of course, Apple looks over at Google's incoming revenue and says "ho hum.")
UPDATE: Both commenters astutely point out that gross is not net - oops. (I did know that, I promise!) Changed headline from "makes" to "brings in."
