Friday Night Death Slot: Shark Tank inverts this; since its move from Sunday to Friday nights, it has garnered more viewers and got renewed for 22 episodes during its second season in that time slot, compared to the <15 of previous ones.
No Budget: B Roll of contestants at their home/business aside, Shark Tank is shot in only three rooms, the lobby, the hallway and the meeting room with the Sharks.
