In traditional photography the photographers were limited by the availability of processing facilities. In remote locations it became all the more difficult. Particularly photo journalists have to deliver the photos to the news desks at the earliest. In 1980 Sony introduced a camera which can save the images to disk and the images can be displayed on the television. Kodak unveiled in 1990 its first commercial digital camera and at that time digital cameras were priced very high and were mostly used in photojournalism.
