Tourism is a $4 trillion-a-year industry, affecting more than 200 million jobs, or 1 in 10 workers. But tourism actually is an old industry, dating back to the first Olympics in 776BC. Even in ancient Rome it was popular to travel up the Nile to Thebes to view the statues.
The first book on travel, aptly called "Travel" was published by Jehan de Mandeville (anglicized to Sir John Mandeville) in 1357. It became a best seller and was translated into 9 languages.
Trips used to be organized by individuals or small groups who accompanied their guests. In 1758, Cox & Kings became the world's first travel agency - not necessarily escorting the travelers to their destination. Thomas Cook (1808 - 1892) also took large groups on tour and then founded his company in the 1860s. The first travel agency in the United States was founded in 1887 by Walter T. Brownell.
Tourism is the biggest industry in most countries - except the United States, where entertainment is the biggest industry.
In 1926 in Scotland, John Logie Baird demonstrated a machine that transmits movie pictures using radio technology, calling it a "televisor." It was based on a 1884 idea by German Paul Nipkow. At the same time, Philo Fansworth was toiling away in San Francisco on his concept for television. The two men met a few months later, and Baird had to agree that Farnsworth's electronic design was the better. They weren't the only ones working on a TV model, though. Vladmir Zworykin, a Russian immigrant to New York, was working on athode-ray tubes, with the backing of David Sarnoff, the tech-savvy marketer who started NBC. In 1928, Farnsworth's television sets made it to the market first, at $75 a piece.
Gray invented the first electronic musical instrument. He had accidentally discovered that he could control sound from a self-vibrating electromagnetic circuit and in doing so invented a basic single note oscillator. The "Musical Telegraph" used steel reeds whose oscillations were created and transmitted over a telephone line by electromagnets. At the same time, around 1874, Bell had also designed an experimental "Electric Harp" for speech transmission over a telephone line using similar technology to Gray's.
