Direct mail (not so "junk"-y) works for some higher-end products. I know American Express has launched some of their more expensive cards through direct mail; luxury car companies use similar tactics; and insurance companies invest a lot in direct mail, as well.

(And direct marketing companies eat their own dogfood, too. Ogilvy & Mather sent sales letters to lots of Fortune 500 executives, in order to get them to pay O&M to send similar letters to other people. It's a great way to bootstrap your own sales pitch: if your pitch is persuasive, it deserves to be.)
