time slot or place in the schedule could be crucial to its success or failure; generally, earlier prime time slots have a stronger appeal towards family viewing and younger demographics, while later time slots generally appeal more towards older demographics. Some time slots, colloquially known as "graveyard slots" or "death slots", are prone to having smaller potential audiences (with one such example in the U.S. being Friday nights), or intense competition from highly-rated series.
