7. The Telephone
Invented by Alexander Graham Bell in 1876, the telephone revolutionized communication by enabling instant voice transmission over long distances. This breakthrough fostered new business, social, and political networks, laying the groundwork for global connectivity. Bell’s first successful telephone call was made on March 10, 1876, when he spoke to his assistant, Thomas Watson, saying, “Mr. Watson, come here—I want to see you.” (history.com) For more details, visit the Library of Congress.
