What major technological advancement revolutionized communication in the 20th century?

The Internet is recognized as a major technological advancement that revolutionized communication in the 20th century due to its transformative impact on how individuals and organizations connect and share information globally. Unlike previous forms of communication such as the telephone, television, and radio, which were primarily one-way communication methods or limited in scope, the Internet introduced an interactive platform where information could be exchanged in real-time among billions of users.

With the Internet, people could not only send messages instantly across vast distances but also access a wealth of information, engage in social networking, and participate in global commerce. It fundamentally changed personal connections, business operations, and access to education and media, making communication more efficient and widespread than ever before.

In contrast, while the telephone and radio significantly improved communication in their respective times by allowing for voice transmission and broadcasting information, they did not provide the same level of interactivity. Television, although influential in delivering visual content to the masses, also served primarily as a broadcasting medium rather than a platform for two-way communication. The unique qualities of the Internet, including its ability to connect users and facilitate instant information exchange, underscore its role as a pivotal advancement in the 20th century.
