answer:I agree with you, and I think that is the case with many television ads as well, along with the “double the offer” deals that are common. My formula for company reliability is P = number of times you have used that product Q = quality of product L = length of ad in minutes N = number of times the phone number / URL is repeated E = Emphasis placed on phone number / URL C = Initial cost of object F = Final cost after whatever “triple/double the offer” deals they have Reliability = (PQ+1)F / (C(L+NE)) Notice that: As the length of the ad trends towards infinity, reliability drops to zero. As the number of “double the offer” deals trends towards infinity, reliability drops to zero. As they place more and more time and emphasis on their phone number, reliability approaches zero
