Steve's Barking; Why are old school retailers in trouble?

Old school retailers are in trouble in the United States because in this computer age they can't implement fast enough. 

Why did't Sears the inventor of the catalog which one can call the original on line selling be quick enough to have challenged Amazon for e commerce. 

JC Penny did fantastic business with it's catalog, it too missed the boat.

Retailers have got to do something in this turnaround age that they must be nibble and quick.

Just clossing down stores is not the answer.

If major retailers think they can make money from their real estate holdings they are in for a rude awaking, unless they can use the real estate to create a new kind of store for themselves, the're distroying more American jobs, and their profits will be slimmer.
