The Linux Journal has some great comments on the state of advertising:

"So what's happening here? Simply put, companies like Google and Overture are blowing away everything the old advertising business holds dear. Beautiful images. Attention-grabbing graphics. Awards. Strategy. Even old conventions like branding--a term Procter & Gamble borrowed from the cattle industry, back when they created mass media advertising in the dawn of commercial radio more than 70 years ago. They're blowing it away by connecting users and advertisers and helping both offer something valuable to each other."
