The commercial I saw today, for example, featured a young guy who had to learn some Chinese. He should have at least spoken a few phrases of Mandarin to prove that Rosetta Stone works.
It's like having diet commercials without the before and after pics (as fake as they seem) of people who lost weight.
Just thinking aloud...
When the Rosetta Stone commercial first appeared, I wasn't watching it but listening to it. The commercial came on again and it was Olympic gold medalist Michael Phelps and he was learning Chinese in preparation for the Olympics (side note, he stripped to speedoes in the commercial. lol). Anyway, I searched for YouTube for the commercial. But instead found a clip of him trying to use the software.
