Lets suppose you read an article in Car and Driver about how magnificent the BMW 3 series is then discover that BMW is one of the magazine's major advertisers. How much credit do you now give to the review?
Now if its in Consumer Reports (no advertisers), or it says an independent study, then it will get my attention.

Now 'm not saying that the study is wrong (I love milk/dairy and will drink it regardless), only that its important to investigate and be an educated consumer.
