More than half of people would quit their cable company if there were actually a decent alternative, according to recent study. Consulting firm cg42 conducted an online survey of over 3,000 current and former customers of the top five cable companies in the U.S. — Comcast, Time Warner Cable, Cox, Charter and Cablevision — and found that a whopping 73 percent feel that cable companies are predatory in their practices and take advantage of consumers’ lack of choice. Its hard to blame the disgruntled customers.
