Bandwagon

The "share a Coke " commercial is an example of bandwagon because it shows an increasing amount of people wanting to be part of the big group of friends buying Coca Cola. This makes you think that in order to fit in and do what everybody else is doing, buying cokes is the answer. This persuades you to buy it because a large number of people drink Coke and always have. This is more an example of pathos because if many people trust/use that specific brand, it must be good.
