Advertising is as much of a cancer as any form of communication. What's happening is that the barrier of entry - better yet let's use the industry terms: the cost reach of advertising campaigns is low thanks to the internet that drove the cost of distribution of information close to 0. So you're just seeing what was once a privileged tool open to the masses - and it's bad. Anyone can have access to it with a credit card. Now just because there's a lot of bad advertising, probably the great majority of it, doesn't mean it's a cancer. Else everything that's abused in a bad way is a cancer.
