Interesting & Controversial


  • 🎂
    Birth of Internet: The Internet was born out of a military project called ARPANET in the 1960s, designed to allow computers to communicate with each other. Interestingly, the first message sent over this network was "LO", which was supposed to be "LOGIN", but the system crashed after the first two letters.
  • 🕵️‍♂️
    Dark Web Mysteries: The Dark Web, a part of the Internet not indexed by search engines, is often associated with illegal activities. However, it's also a haven for political dissidents and journalists in oppressive regimes, providing a platform for free speech and anonymity.
  • 🚨
    Cybersecurity Breaches Impact: Cybersecurity breaches have had significant impacts, both financially and socially. For instance, the infamous WannaCry ransomware attack in 2017 affected over 200,000 computers across 150 countries, causing billions of dollars in damages.
  • 🚫
    Internet Censorship Worldwide: Internet censorship varies greatly around the world. China's "Great Firewall" is perhaps the most well-known example, blocking access to many foreign websites. On the other hand, countries like Estonia have made Internet access a basic human right.
  • 💰
    E-commerce Boom: The E-commerce industry has seen an unprecedented boom, with global sales expected to reach $4.9 trillion by 2021. Interestingly, the largest single-day online shopping event is China's "Singles Day", which in 2020 generated over $74 billion in sales.
