Let's take a closer look at Saturn.
In 2005, according to Nielsen Monitor-Plus, GM spent $215 million advertising its Saturn brand.
Saturn's profit that year: $0.
Saturn had a strong following of enthusiastic customers when it launched in 1990, but here's the problem: the cars never made a profit. Not even Goodby, Silverstein's award-winning advertising could fix an unprofitable business model. Advertising never can.
