In the case of TV Land, Mr. Margolis said, the campaign was seeking to reach “folks who may not be as political, may not be deciding until later.”

“A lot of these people are lower-information voters,” he said, “not necessarily tuned to politics and watching a little more programming that is out of the main lane of what most of us think of.”
