Take the Playstation for example. If you watch T.v what console are you going to see an advert for........the Playstation of course. Now have another think what is the most popular console in the world today....again the Playstation. See the connection. Sony are continuing the trend with them Ps2 adverts going on about some "3rd place".
Ok maybe Nintendo do have one or two adverts a year, but they are mainly for their cartoony brands of game. E.g Pokemon and DK. This just strenghens the childish Nintendo image that they are so desperate to get rid of. Basically they have screwed themselves.
Sega on the other hand. Can you actually ever remember seeing a Dreamcast advert. Nope I didn't think so. Look where it is now. Another example that proves my point.
Basically Sony have already released their console and begun their advertising campaigns and I think Nintendo should follow suit. Possibly a mass advertising campaign a month or two before the Gamecubes release. Just to make sure everyone is aware of the new technology being made available to them. What about Microsoft I hear you say. Well considering the vast amounts of money they have I think you can guarantee huge amounts of advertising coming from them.
The key factor will be though how much they grab you and get you to think about it. Take the Ps2 ads. You dont actually have a clue what is being advertised right until the end when Ps2 is flashed onto the screen. And what exactly does the "3rd place" actually mean. Nintendo and Microsoft shoulf follow this tradition but with something fresh and new.
