If you don’t know why, then you’re reading the wrong blog. The New Agenda is keeping tabs on sponsors of David Letterman’s show. I have already told T-Mobile that I will cancel may $120 month service (paying the penalty) if they don’t stop advertising on The Late Show by July 15. Top names on the boycott list: * Johnson & Johnson * T-Mobile * Ford * Nissan/Infiniti * Toyota/Lexus * Proctor & Gamble * Citigroup (which should be out of business, anyway) * Chase (JPMC) * The Gap (plus Old Navy and Banana Republic) * Wyeth * Saturn * Hotels.
