Yelling TV Ads

One of my pet hates is TV ads where the advertiser yells out of the screen. There are at the moment only a couple of these type of advertisements on ITV TV, I only hope it isn't the foretaste of a trend. I wonder what they hope to acheive. It does not make me want to buy their products, in fact quite the reverse, I will avoid those particular products like the plague.

Advertisers who need to shout their wares make me question their companies and products. I don't feel that the yelling is because the company is excited about it's product but rather that they perhaps are desperate.

I wonder if other people feel the same as I do? Do TV adverts where the ad presenter shouts turn you off too?
