The 50 Who Matter Now

In our second annual ranking, Business 2.0 has compiled an unabashedly subjective list of people, products, trends, and ideas that are transforming the world of business.

John Chambers
John Chambers
CEO, Cisco Systems

Rank: 9

Why he matters: Thanks to the white-hot market for video content, which drives up bandwidth demand, sales of Cisco's switches and routers are booming. But Chambers is positioning the networking giant to be more than a Silicon Valley merchant of picks and shovels.

He also wants Cisco to increase its visibility with consumers, and to do that he's launched a targeted acquisition spree, buying, among others, TV set-top-box maker Scientific-Atlanta, e-mail security company IronPort Systems, and Internet conferencing leader WebEx Communications. Will it pay off? The jury's still out, but in truth, it might not matter. When you're in a gold rush, owning the market for picks and shovels isn't such a bad thing.
