This is the California Milk Processor Board campaign, begun in 1993.
This is the National Fluid Milk Processors Promotion Board campaign, begun in 1995:
Two different clients. Two different campaigns. Unfortunately, consumers never did realize the difference. Fortunately, both clients realized that fighting to differentiate their campaign was counter-productive. And so in 1998, we started seeing with this:
Another example where consumers know best. Yeah, baby!

The slogan "got milk?" was licensed to the National Milk Processor Board (MilkPEP) in 1998 to use on their celebrity print ads - ie; smaller clients campaign proved so successful it was added to larger (national) clients campaign - even though the dimwits kept doing that sad moustache thing thus making the line do nothing.
I don't read it as consumers made them merge the campaign, I read it as national client didn't have the balls (or ability because they were under moustache-contract with another agency on the ast coast) to run the highly succesful campaign that ran in California. These are two different campaigns from two different agencies on two different coasts to begin with.
The truth is, the public is rarely as interested in the minutia of advertising as ad people are, and to their credit, both milk groups realized that they'd both benefit by not fighting the consumers' perception.
And no, the "Got Milk?" line didn't really add anything to the milk-mustache visuals, but at that point in the campaign, it didn't really need to.
