It caters to a certain part of the population respectfully by giving an alternative to other foods, and it increases sales due to getting more customers which being catholics, couldn't normally have McDonald's on a Friday, so it opens up another day of the week for McDonald's to be enjoyed by certain types of consumers.
Yes, it's a great marketing ploy that McDonalds created Filet o'Fish because it was a fun way to give the Catholics fish that they wanted to eat on Fridays. It's a fun way that they made the product so that they could find a way to literally cater to a large segment of the population.
The filet fish is the biggest rip off on McD's menu. Way over priced. That $4 sandwich should be about $1.50 which the fish filet cost McD's only about 20 cents so the markup is unreal. The Filet-O-Fish isn't just a popular item in the U.S. The sandwich is now served overseas in countries like Russia, Japan and India.
The Filet o' Fish is not the best marketing ploy ever. It is certainly a good marketing move to ensure that more people are in the demographic to eat at McDonald's due to religious observances. However, it simply falls in the realm of expanding menu offerings, and cannot be qualified as the best ever.
No, the Filet o' Fish is not the best marketing ploy ever. Most people have never heard of this reason why the Filet o' Fish was created. Furthermore, most people believe that Catholics can eat anything they want on any day they want. A good marketing ploy is one that a large number of people have heard of.
