Looks like there might be a good reason NOT to refer to the A's stadium by its ridiculous corporate moniker, besides the fact that O.co Coliseum is just a stupid name to begin with. Seems the A's are not referring to it as O.co Coliseum either. To be honest I hadn't noticed until it was pointed out by the Oakland Tribune, but since Overstock.com, now O.co, took over the naming rights, the A's have not been calling the stadium by its purchased name beyond 3x in every radio/tv broadcast as is their contractual obligation vis-a-vis their lease. Rest of the time they've simply been calling it some combo of the Coliseum, Oakland Coliseum or Oakland-Alameda County Coliseum.
Why you might ask? Do the A's have some high and mighty opposition to corporate names? Sadly no (come on they went along with the 10 year Network Associates/McAfee naming after all). It's really all about the money. Apparently the deal that put the O.co name on our old donut of a stadium was made between the city, Coliseum management group SMG, the Raiders, and O.co. The A's were not party to the agreement, nor do they get any financial gain from it. As a result the A's have maintained the stadium's name is Oakland-Alameda County Coliseum in all team communications. Indeed a quick perusal of the A's website will find no mention of O.co Coliseum. It's either referred to by it's full proper name that it has had since 1966 or simply as the Coliseum. So here's hoping that SMG, the city, and the A's remain adversarial about this for some time. Because the longer they do, the longer the stadium is really the Oakland Coliseum in more than just our hearts, but in fact, on baseball game days.
