I believe the uniform grass lawn game about because some company invented by accident an herbicide and had to figure out a marketable use, so began an ad campaign to claim that lawns “needed” to be uniform in order to sell their product.

I read this somewhere when I was researching how to care for my clover covered lawn but I’m fine with it now.
