I doubt it's possible to fix. Advertising is by its nature an attempt to manipulate people, by grabbing their attention, bombarding them with information, and eliciting emotional responses in them. Unsolicited advertisement is inherently disrespectful to the people being advertised at. There's no way to do it nicely, you can only hope people are too apathetic to complain about it.
Advertising is about moving product. Just a quick perusal of advertising techniques indicates that just "providing information" is a rarely used methodology. Biased information isn't very useful anyhow.
Indeed. Putting a scantily-clad lady up on the TV screen isn't giving me any information. It's treating me like an animal, hoping my sex drive overrides the part of my brain that says "You don't really need to buy this crap".
Loud noises, cute kittens, catchy songs, scary consequences, status symbols, repetition until you can't forget the company's name if you tried. That's not any information I need.
