The Internet (1969)

The internet has reshaped daily life faster than any invention except the printing press, transmitting its first message in 1969 and reaching one billion users by 2005—twice as fast as the telephone's adoption. Tim Berners-Lee's World Wide Web opened in 1989, enabling $4.9 trillion in global e-commerce by 2022 and instant global communication. It surpasses #3 the steam engine in sheer scale of personal impact, connecting 5.4 billion people as of 2024.
