LOS ANGELES—A coalition of more than 20 million television viewers issued a strongly worded statement Monday expressing outrage at the timing of a commercial break that interrupted the program they were watching just as it reached its most compelling point. "Due to what can only be described as gross incompetence, this poorly placed advertising block left us with little option but to sit through the commercials in their entirety so that we would not miss any part of the show when it returned," the statement read in part. "We sincerely hope this unfortunate incident is not repeated, especially right before we find out whether or not contestants on our favorite game shows are going to win big money." TV viewers last mobilized in December, when a late-night program that at first appeared to be a television talk show was later revealed to be a 27-minute-long advertisement for a juicer.
