Invest sucessfully in the companies that will prevail through thechnology booms and busts -- with indispensable advice from the world's most trusted business publication, The Wall Street Journal.

There's no doubt the Internet has changed the way we live, the way we work, and the way we invest in the new millennium. But while many investors made fortunes investing in technology companies while the Intenet stock bubble was inflating, countess others lost their shirts when the bubble finally popped.

Now, Stephen E. Frank -- a veteran of The Wall Street Journal and CNBC -- explains what we need to know about investing in Intenet and technology stocks in today's postbubble economy. In Networth, Frank lays out a straightforward framework for understanding how the Intenet works, now different business models stackup, and how to think about technology stacks as part of a broader investment portfolio. He weighs in on the potential risks and rewards of each Internet subsector, and profiles a slew of dot-com companies, from obvious candidates like Amazon.com to transformed titans of the old economy like United Parcel Service.
