Tear down those walls, Time Warner (TWX) and Ziff-Davis (ZD) ! Two forward-looking companies, same day, reached the same conclusion: The only way to realize the value of their Internet holdings is to get rid of their non-Net holdings!

No one is buzzing about these two companies' decisions as a trend ... yet. But they will. Because what it says is that the "fad" of Net valuations is not going away. People want to invest in and give capital to companies that are Net-savvy with no baggage. They don't want to invest in hybrids or companies that are somewhat committed to the Web.

By getting rid of the Time Warner stores, Gerald Levin is saying, "Look, this Net business is going to put out of business traditional high-end merchandising with its expensive rents and expensive help. We have to get out of it before it is worth nothing."

ZD is taking a more radical step. It wants to leave its core magazine competence because it knows that magazines are a loser. Interestingly, there seems to be no Old Guard contingent at ZD who is willing to stand in the way of the New World. Can you imagine this kind of discussion at

Hearst

or

Conde Nast

or even, shudder, the

Time

portion of Time Warner?

Not now. Not yet.

I know it will happen. They know it, too. The only reason why it hasn't happened yet is because these old businesses generate enough cash that the managements can't sacrifice them. But when that cash flow gets crimped by rising coated freesheet and delivery costs, as well as a lowered rate base from fewer readers, you will see this kind of thinking repeated everywhere. If it doesn't, then I have misjudged the direction of

Lucent

Intel

(INTC) - Get Report

,

Hewlett-Packard

(HWP)

and a host of other companies that are bent on destroying the profitability of traditional print and bricks and mortar. (It's no longer just me anymore!)

Unfortunately, I don't think it will be that successful because, as I never tire of saying, the Internet is a mindset as well as a business model. Two weeks ago, when the

Financial Times

rolled out its ad campaign featuring some guy sticking his head in a bucket -- I don't know, beats the heck out of me -- I emailed my favorite writer there. I asked him if this campaign signaled the beginning of more interactivity among the people who put out the

FT

and the people who read the

FT

.

Still haven't gotten a response.

Figures.
