When were the following invented ?
Radio :
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.
Film :
The history of the film began in the 1890s, with theinvention of the first motion-picture cameras and the establishment of the first film production companies. The films of the 1890s were under a minute long and until 1927, motion pictures were produced without sound.
Television :
TELEVISION is one of the greatest technological advances of the 20th century.
It was invented by a Scotsman who funded his initial experiments by working as a shoeshine boy and a razor blade salesman.
Several inventors in the USA and Europe were experimenting with television systems in the early years of the last century.
Some worked on all-electronic versions, but Scottish-born John Logie Baird (1888–1946) used a partly mechanical approach.
Telephone :
Alexander Graham Bell's telephone patent drawing, March 7, 1876. The first successful bi-directional transmission of clear speech by Bell and Watson was made on March 10, 1876 when Bell spoke into the device, "Mr. Watson, come here, I want to see you." andWatson answered.
Internet :
ARPANET adopted TCP/IP on January 1, 1983, and from there researchers began to assemble the “network of networks” that became the modern Internet. The online world then took on a more recognizable form in 1990, when computer scientist Tim Berners-Lee invented the World Wide Web.
Cell Phone :
On April 3, 1973, Motorola employee Martin Cooper stood in midtown Manhattan and placed a call to the headquarters of Bell Labs in New Jersey. The first mobile phone call was made 40 years today, on April 3, 1973, by Motorola employee Martin Cooper.
Cds :
The first commercial compact disc was produced on 17 August 1982. It was a recording from 1979 of Claudio Arrau performing Chopin waltzes (Philips 400 025-2). Arrau was invited to the Langenhagen plant to press the start button. The first popular music CD produced at the new factory was The Visitors (1981) by ABBA.
DVDs :
DVD ( "digital versatile disc" or "digital video disc"[4][5]) is a digital optical disc storage format, invented and developed by Philips, Sony, Toshiba, and Panasonic in 1995. DVDs can be played in multiple types of players, including DVD players. DVDs offer higher storage capacity than compact discs while having the same dimensions.
MP3s :
In 1987, the prestigious Fraunhofer Institut Integrierte Schaltungen research center (part of Fraunhofer Gesellschaft) began researching high quality, low bit-rate audio coding, a project named EUREKA project EU147, Digital Audio Broadcasting (DAB).
Blue ray's :
When the CD was introduced in the early '80s, it meant an enormous leap from traditional media. Not only did it offer a significant improvement in audio quality, its primary application, but its 650 MB storage capacity also meant a giant leap in data storage and retrieval. For the first time, there was a universal standard for pre-recorded, recordable and rewritable media, offering the best quality and features consumers could wish for themselves, at very low costs.
