Budweiser Vs. Miller

I've seen a lot of Bud and Miller comercials going on recently. I don't think this is really a conspiricy so I'm putting this in BTS instead of ATS. I've noticed that Miller is using an advirtisement were referees switch Budweiser with Miller, and then Bud has a commercial were the refs wanted the Budweiser for themselves. In their commercials they constantly jibe at each other. I think that they have a secret agreement so that they both get lot's of sales and double the advirtisement.
