He’s not a
household name like Gates, Jobs, or
Zuckerberg. His face isn’t known to millions. But during his remarkable 20-year
career, no one has done more than Marc Andreessen to change the way we
communicate. At 22, he invented Mosaic, the first graphical web browser—an
innovation that is perhaps more responsible than any other for popularizing the
Internet and bringing it into hundreds of millions of homes. He cofounded
Netscape and took it public in a massive (for that time) stock offering that
helped catalyze the dotcom boom. He started Loudcloud, a visionary service to
bring cloud computing to business clients. And more recently, as a venture
capitalist, he has backed an astonishing array of web 2.0 companies, from
Twitter to Skype to Groupon to Instagram to Airbnb.
