I've rarely seen this topic kicked around. The commercial plugs have always been there but are becoming more blatant. Notice whenever someone unpacks a grocery bag or takes something out for a snack, the package is conveniently positioned to make the product name totally visible to the camera. OK, we know this goes on, the product manufacturers pay for this. But last Thursday's episode took this to new heights (actually, depths, IMHO): first, at the newsstand where Elaine meets the "no children" guy, there is a shot of the newsstand where the shelf above the newspapers contains lots of candy, etc., all conveniently obliterated as to product name, except there is pure clarity is the yellow box of M&M's, standing out on its own. This is CRASS. Of course, the plug later on when Jerry tells George he should be represented by the M&M figure is accompanied by a perfect camera shot on the figure that lasts a bit long. If you have the episode on tape, you can check this out. The attempt is always there to push this stuff as much as possible without seeming obvious, but this time, as Kramer would say, OH IT WAS OBVIOUS.
I'm only pointing this out because I think it cheapens the look of the show. I can't imagine the money makes that much of a difference.
