Why would Nikon advertise there? I mean, sure, it may convince a few people that everyone in there is using a Nikon... But why would that convince people that a P&S would be just as effective as those professional level?
Nikon ads are ALL over the stadium. A guy walks around with a D50 and takes photos of everyone who asks, then hands them a slip of paper that shows where they can view the shots on redsox.com (eventually takes you here.) Kinda neat!
Nothing against Nikon at all here, I'm just saying it's a funny shot.
According to the industry insider, Canon has such a strong brand and market position that it just sets up the camera market and the rest of the camera makers just follow Canon to keep up with the market. I know this is a generalized take at this but I think there is a truth to that. I think Canon does not have to out-bit Nikon on that ad spot as it is very apparent by looking at that picture.
