 * Kodak Brownie Camera** is the name of a long-running and extremely popular series of simple and inexpensive cameras made by Eastman Kodak. The Brownie popularized low-cost photography and introduced the concept of the snapshot. The first Brownie, introduced in February, 1900, was a very basic cardboard box camera with a simple meniscus lens that took 2¼-inch square pictures on 117 rollfilm. With its simple controls and initial price of $1, it was intended to be a camera that anyone could afford and use, leading to the popular slogan, "You push the button, we do the rest." The camera was named after the popular cartoons created by Palmer Cox.

A **fixed-wing aircraft**, typically called an **airplane**, **aeroplane** or **plane**, is an aircraft capable of flight using forward motion that generates lift as the wing moves through the air. Planes include jet engine and propeller driven vehicles propelled forward by thrust as well as unpowered aircraft (such as gliders). Fixed-wing aircraft are distinct from ornithopters in which lift is generated by blades and rotary-wing aircraft in which wings move relative to the aircraft.

**Guglielmo Marconi**, an Italian inventor, proved the feasibility of radio communication. He sent and received his first radio signal in Italy in 1895. By 1899 he flashed the first wireless signal across the English Channel and two years later received the letter "S", telegraphed from England to Newfoundland. This was the first successful transatlantic radiotelegraph message in 1902.


 * Movie Theater-**The first public exhibition of projected motion pictures in the United States was at Koster and Bials Music Hall on 34th Street in New York City on April 23, 1896. However, the first "storefront theater" in the US dedicated exclusively to showing motion pictures was Vitascope Hall, established on Canal Street, New Orleans, Louisiana June 26, 1896—it was converted from a vacant store.A crucial factor was Thomas Edison's decision to sell a small number of Vitascope Projectors as a business venture in April-May 1896. In the basement of the new Ellicott Square Building, Main Street, Buffalo, New York, Mitchell Mark and his brother added what they called Edison’s Vitascope Theater (entered through Edisonia Hall), which they opened to the general public on October 19, 1896 in collaboration with Rudolph Wagner, who had moved to Buffalo after spending several years working at the Edison laboratories. This 72-seat plush theater was designed from scratch solely to show motion pictures.

I think that the Marconi radio was the most important invention of all the above inventions. When he proved that radio communication was easily done, it opened door ways to a new way of communication.
