This set of communication protocols allowed different networks to connect and communicate with each other, creating a unified global network.
In 1983, ARPANET officially adopted TCP/IP, marking the transition from a closed network to the modern internet. This standardization was crucial for the internet's growth, as it enabled diverse systems to interoperate seamlessly. By the end of the decade, the internet had begun to expand beyond academic and military use, setting the stage for its commercialization.
**The Birth of the World Wide Web (1990)**
While the internet was invented in the 1960s, the World Wide Web (WWW) was a later innovation that revolutionized how we use the internet. In 1990, British computer scientist Tim Berners-Lee invented the World Wide Web while working at CERN, the European Organization for Nuclear Research. The WWW introduced a system of interlinked hypertext documents accessible via web browsers, making the internet more user-friendly and accessible to the general public.
It's important to distinguish between the internet and the World Wide Web. The internet is the global network of interconnected computers, while the World Wide Web is a service that operates over the internet, allowing users to access and share information through websites and hyperlinks.
**The Expansion of the Web (1990s)**
The 1990s were a period of explosive growth for the internet, driven by the widespread adoption of the World Wide Web. The development of web browsers like Netscape Navigator made it easier for people to navigate the web, while search engines like Yahoo and Google helped users find information quickly.
During this time, the internet began to transition from a tool for researchers and academics to a mainstream phenomenon. Businesses started to establish an online presence, and e-commerce began to take off. The internet was no longer just a network; it was becoming a global marketplace and a platform for communication and entertainment.
**The Dot-Com Boom (Late 1990s)**
The late 1990s saw the rise of the dot-com boom, a period of rapid growth for internet-based companies. Startups with ".com" in their names flooded the market, and venture capital poured into the tech industry. Companies like Amazon and eBay emerged as pioneers of e-commerce, while others focused on creating new online services and platforms.
However, the dot-com bubble burst in the early 2000s, leading to the collapse of many overvalued companies. Despite the crash, the dot-com era laid the groundwork for the modern digital economy, demonstrating the internet's potential as a platform for innovation and entrepreneurship.
**The Evolution of Social Media (2000s)**
The 2000s marked the rise of social media, which transformed the internet into a more interactive and social space.
