At least according to this story. Looks like that rainy day may be coming for Giants owners. I wouldn't expect any major short-term impact, but losing a slice of the Silicon Valley ad-revenue pie, and seeing the next generation of South Bay fans flock to the A's is bound to put a crimp on the Giants' long-term earning potential. The question is, how big of one? No news of any potential buyout of the Giants' rights.
