GM cancels auto show is the first sign that there is recognition of the "new world order" of advertising.  No longer is the ad agency media campaign building false momentum going to sell product.  The sooner the retail industry is aware of this, the better sales per ad dollar spent they will be achieved. 

The consumer is changing, they do not have the money for many of the marketing tactics used by the agencies.  Value for the money spent is what consumers will demand is the future; not how bad or good you can make me feel about myself.  We can see it starting in the auto industry with what cars consumers are buying and why consumers are buying those vehicles.  Consumers today are going to the internet, learning about the products themselves and comparing products and manufacturers.  They/we consult with each other about purchases and share experiences about the products performance:  Good or bad.  (sometimes instead of looking at who is not buying or how much sales are falling, look at who is buying and why, incredibly revealing about the future) 

The new world order in retail is consumer information and those retailers and manufactures that make it easy to find quality information over the internet that consumers trust will win and win big.

Who benefits - search of course and data management services, digital delivery companies (cell, cable, wireless) will continue to see bandwidth use increase, devise manufacturers to some degree but most of us already have a portable digital device, it is just a matter of upgrade and replacements.  The retailer and or manufacture who masters "just in time advertising" or "advertising on demand" will be the biggest winner.

Biggest loser, those who fail to adapt of course but the advertising industry is going to experience a dramatic metamorphosis or cease to be.
