Why is it?

A man wakes up in the morning after sleeping on an advertised bed, in advertised pajamas. He will bathe in an advertised tub, wash with an advertised soap, shave with an advertised shaving cream, eat a breakfast of advertised juice, cereal, and toast(toasted in an advertised toaster), put on advertised clothing, and glance at his advertised watch. He will ride to work in an advertised car, sit at an advertised desk, smoke advertised cigarettes, and write with an advertised pen. Yet this man hesitates to advertise, saying that advertising does not pay. Finally when his unadvertised business goes under, he will advertise it for sale.
