Its first operational service began on April 7, 1968, marking a significant advancement in hovercraft technology.

The exclusive right to make, use, or sell an invention is called a patent. A patent grants the inventor the legal authority to prevent others from commercially exploiting their invention without permission for a specified period, typically 20 years from the filing date. This protection encourages innovation by allowing inventors to potentially profit from their creations.

Cup phones, also known as cup telephones, were invented in the early 19th century. The earliest known reference to this type of communication device dates back to 1816 when American inventor Charles Wheatstone described a device that used a taut string to transmit sound between two cups. This simple form of communication demonstrated the basic principles of sound transmission and laid the groundwork for later developments in telecommunication.

Robert E. Kahn, along with Vint Cerf, co-invented the Transmission Control Protocol/Internet Protocol (TCP/IP), foundational technologies that enable the internet's operations. Their work laid the groundwork for global digital communication, facilitating the growth of the internet as we know it today. Kahn was recognized with the National Medal of Technology for his significant contributions to advancing technology and enhancing the nation's competitiveness in the digital age.

The invention of the electric light bulb made it possible for factories to stay open at night. Introduced by Thomas Edison in the late 19th century, electric lighting allowed for safer and more efficient working conditions after dark. This innovation extended production hours, significantly increasing productivity and contributing to the growth of industrial economies.

During the Han Dynasty (206 BCE – 220 CE), China saw the development of traditional puppetry. The use of puppets was primarily for entertainment and storytelling, often incorporating elements of folklore and mythology. This art form evolved over centuries, leading to various styles, including shadow puppetry and string puppetry, which remain popular in Chinese culture today. Puppetry has played a significant role in preserving cultural narratives and artistic expression throughout Chinese history.

The Gutenberg revolution of printing in the 15th century dramatically transformed the dissemination of knowledge and information. It enabled the mass production of books, making literature and scholarly works more accessible to the general public, which contributed to increased literacy rates. This innovation played a crucial role in the spread of ideas during the Renaissance and the Reformation, ultimately fostering a more informed and engaged society. Additionally, it disrupted the traditional manuscript culture, leading to significant changes in education, religion, and the arts.

The concept of the inland letter, which is a type of postal service for sending letters within a country, was developed as postal systems evolved over time. While no single individual is credited with its invention, the establishment of organized postal services in the 19th century, such as those initiated by countries like the United Kingdom with the introduction of the Penny Black stamp in 1840, facilitated the use of inland letters. Various postal reforms across different nations contributed to the standardization and accessibility of inland letter services.
