You've seen it with your own eyes.
Circuit City you used to go to get some CDs and other gadget closed down, bankrupted, and only its online (webstore) is remained with different owner.
You've also seen BlockBusters you used to frequently visit on Friday night or Weekends to rent some DVDs are closing down one by one.
These big chain retailers just failed to adapt into the new world of digitalization.
There must have been thousands of people worked for these firms became unemployeed because its management could not think ahead.
Competition strategy should not stop. The management should always seek for a better way to compete and survive tomorrow.
The book introduced by one of competitive strategy class professors in Haas, Competing for the Future by Gary Hamel and CK Prahalad explains all these situations.
Now, enough about sightseeing.
What will happen when these retailers close down?
Will the market shrink on that selected sector?
Do people rent fewer DVDs because Blockbusters is no longer with them?
Do people buy fewer books because B&N is not near by their houses?
Do people buy fewer clothes because many big Macy stores are closed down?
No, the buyers simply moved to some other means to purchase goods they want.
In fact, each market size of these other means is growing rapidly.
The spending power of individual consumer has got stronger and it is still.
The market size did not change, but the market leader is changed.
Movie Rental? Coinstar (CSTR)'s RedBox $1 dvd rental vending machine in super markets, and NetFlix (NFLX) online+DVD delivery has grabbed this huge market.
For book, Amazon will take the market share that B&N will lose.
We gotta invest in these type of businesses.
The upcoming market leader.
It's no longer Retail is Retail and Virtual is Virtual.
Retail is losing so its market itself is fusing into Virtual's.
And in that fused market, there will be a new leader.
Invest in that leader.
