There's been "phoner" commercials for years. People are used to them by now. At least I hope they are not confused any more. It's pretty apparent they're not really calling into The Dinovite Minute-Long Show, then calling back in five more times that hour on every talk station. Most of the phoner commercials are so obviously faked they seem awkward and unnatural. There was one recently about some male libido pills that had two male voices, and if you listened, it was obviously the same guy doing both voices. I don't even remember what the commercial was for, I just remember listening for the similarity in both "callers" after I first noticed it.
Sam Waterston from Law & Order does a PSA for the National Parks or some government agency that's a phoner. It's a straight read, and at the beginning he even says "I'm calling to tell you about..." as if he's called into the middle of the other PSAs our local talk station runs incessantly. It's just a variation of the ways commercial producers break up the monotony of same-voice-same-tones-reading-liner-copy that many commercial breaks end up being. I guess it's better than the unnatural conversation commercials where a teenager and parents are talking and it starts out with "Mom, do you ever get that not-so-fresh feeling?"
