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.

Randall Stephenson
Randall Stephenson
Chairman and CEO, AT&T

Rank: 21

Why he matters: Stephenson hopes to transform a company rooted in yesterday's technology -- telephone landlines -- into a multiplatform provider of telecom services. AT&T's decision to rebrand the Cingular network with Ma Bell's 122-year-old moniker got a big boost with the news that AT&T would become the exclusive carrier of Apple's iPhone.

But Stephenson must also find success with the U-verse -- a long-delayed IP-based television system that will put AT&T in direct competition with cable companies. In May, AT&T announced that it will spend $6.5 billion ($1.4 billion more than previously announced) to roll out the system in 20 cities. If the effort fails, Stephenson could go the way of the rotary dial.
