Perhaps I should apologize for using the term "pimp" here. It's not exactly a tech term; but has the traditional (US) meaning of a "seller of illegal, illicit, immoral merchandise and/or "services" - having no regard for the value to the buyer or harm to those who actually provide the service and interested only in how much money can be extracted." I.E. here - the "advertising industry" as it shows up on the internet.
Deliberately sarcastic and derogatory.
My apology is for the use of sarcasm here, not for my opinion of those who push the advertising.
