It's been so long since I delved into this I can't remember what I used to call it - but people should have the ability to opt out of types of ads and opt in to other types with fine grain control.. this would make the ads delivered more valuable too. give people the option to turn off moving ads, turn off ads for alcohol, gambling.. opt in to 'cat ads' or opt in to getting amazon ads on pages - or something - this way there are options and control and no longer have to say 'no one likes ads'. I've written longer and more detail with similar in the past.
