Local cable and Internet companies (cough, Time Warner) frequently become the object of scorn and derision by their customers. A lack of competition leaves customers frustrated by billing and service issues, and feeling like their cable provider has no reason to rectify their concerns. Enter Google Fiber. Since the Internet search-engine giant moved into the fiber-optic business and made Kansas City its test market, companies like Time Warner seem to be caught after years of near-monopoly business conditions. And the reason is clear: Google is a vast upgrade in television-picture quality, Internet speeds and customer service. Google is the Cadillac of local cable service, but the price is more like a Buick and undercuts similar plans offered by competitors — like Time Warner.
