Execution matters.
Fuji posted this spot on youtube on February 19, 2013.
And Mercedes-Benz posted the following on September 23, 2013.
I believe in coincidence. And I've have seen different teams come up with the exact same idea and different agencies pitch similar campaigns more than once. So I don't care if someone saw the other spot before executing theirs. What's interesting to me is if they did something to make it their own and make it better.
(I just saw both of these spots on AdTeachings.com, Suzanne Pope's fantastic blog. You should also follow her on twitter @SuzannePope.)
UPDATE:
The team behind the Mercedes spot, Art Director Lucas Osis and Copywriter Nico Baumann, were interviewed by Teressa Iezzi in this Co.Create article about how they made the spot.
Of course, this quote jumped out at me.
"We then remembered a video we’ve seen a while ago: a guy moving a chicken around while its head stood perfectly still: Exactly the same thing the Mercedes system is able to do. (A perfect analogy! But above all we wanted to create something that we would really enjoy to watch. So we tried to improve it somehow and thought: What’s better than seeing a chicken shaking? A chicken that is shaking to some funky disco music of course! And hopefully, people will agree with us."
I don't care if they saw the Fuji spot or one of other random chicken head videos on the internet. The key is this phrase, "So we tried to improve it somehow..."
