Marc Andreessen’s journey into the tech world began at the University of Illinois at Urbana-Champaign, where he worked at the National Center for Supercomputing Applications (NCSA).
It was there that he co-created Mosaic, one of the first web browsers to feature a user-friendly interface, including images and text on the same page, an innovation that helped bring the internet to the masses.
Recognizing the potential of the web, Andreessen teamed up with entrepreneur Jim Clark to launch Netscape Communications Corporation in 1994. Their flagship product, Netscape Navigator, quickly became the dominant web browser of the early Internet era, setting the stage for the Internet boom.
Netscape’s success led to a high-profile IPO in 1995, one of the defining moments of the dot-com era. However, the company soon faced fierce competition from Microsoft, which bundled Internet Explorer with Windows, leading to the infamous “browser wars.”
Despite the challenge, Netscape’s impact was undeniable. It pioneered innovations in web browsing and laid the groundwork for the open web we know today.
