1995 was the year.

• The first digital cameras came on the market in
  1995.
• Made by Kodak and Apple Computers, each camera

  film was not required, these cameras were popular
  with small businesses, realtors and others that
  needed immediate photos.

More and more professions began using digital
images.

• The medical field and newspaper photographers
  were just two professions that wanted to use
  digital photos instead of waiting for darkroom
  development of film.

  film will soon be a thing of the past.

  devices for space photography. Astronomers could
  now take photos in seconds that would have taken
  hours.
• 1990s Digital cameras became affordable.
• Today CCD photography chips are being used in
  the Hubble telescope and the Mars Rover. Phones,
  PDAs and toys all have digital cameras embedded
  in them.
