I don't trade commodities, maybe this is why I fail to see the value of those CME commercials. I know the CME went public recently, is this why? What is the point of raising public money for an exchange? I guess I question the NYSE commercials equally. Has this improved anything from a trader's standpoint since the exchange made a public offering? (I've also wondered why the NYSE runs ads, or Nasdaq for that matter when they used to).
