Another Olympics extravaganza has come and gone, and once again viewers were subjected to a deluge -- or should that be de-luge? -- of reruns from advertisers. That has been my complaint for years, after every iteration of the Games, Winter or Summer: The same commercials are shown over and over and over again, leaving viewers bleary-eyed and wondering whether Madison Avenue agencies are rationing creativity. Even spots that are special or imaginative wear out their welcome after being run countless times. But because I do count, it appears that the problem is getting worse.
