Commercials have been part of TV since the beginning.

Traditional advertising whether on a billboard, magazine page, radio, TV are benign afaic, annoying, but benign. Advertising on the internet is an insidious evil because of what is happening behind all those pretty little pictures. Not only are they attempting to sell you product, they are stealing your data to bolster the profits of said company, without giving you due compensation. If my data is so valuable to corporate America, then it's worth a mint to me and until they cough up the $value$ I determine for my data created with my labor, I'm going to keep as much of my data out of their hands.
