The other reason the company's don't go out of business is they are corporate owned. Purina is owned by M&M/Mars, Iam/Euk by Proctor and Gamble, Hills Science Diet by Colgate Palmolive, Pedigree by Nestle..........and the list goes on. With that kind of backing they will forever be in the store with multi million dollar add campaigns to support them. There will always be ignorant people out there that will buy their products cuz they see it in print and on tv. I tell people all the time, if you see adds for a food, run. They spend more in advertising than some small co. make in a year. The only places I see the quality foods advertise is in the holistic type publications. And you won't see the big names in them.
