Customer satisfaction with subscription television and internet service deteriorated even further this year, according to a large survey of Americans.

The two industries scored lowest among those tracked by the American Customer Satisfaction Index. Satisfaction with pay TV fell 4.4%; internet service declined 3.1%.

Comcast and Time Warner Cable, which are seeking to merge, are the worst-performing providers of both television and internet service. Cable companies generally scored lower than fiber-optic and satellite operators like AT&T and DirecTV, which are also seeking to merge and were at the top of the list for television service.

The survey is based on interviews with about 70,000 Americans. Scores are indexed against general satisfaction with other consumer industries.
