One thing I'd like to point out is that, display an ads usually doesn't make the situation worse. So neutral and negative are (mostly) the same for a brand because they don't convert to a sale, while positive does. For example, if you feel sick about a specific ad, you probably won't be interest in that brand anyway regardless if you see the ad or not. And this is the worst case, "they failed to give good impression to someone". The best case is, it might remind someone about the brand and lead to a sale in the future.
There're several technics in ad industry to minimal the negative effect. One example is frequency cap, which is the total number of times a specific ad be shown to someone. Anyone will get sick if they saw the exact same thing 10 times a day. Another example is ad rotation, means showing slight different ads about the same thing to people. If you like cars you might remember a recent ad campaign about ford focus on youtube.
Do these technics work? Well I don't think it makes a negative experience positive, but it does make some of them neutral for me.
