Throughout the history of photography, technological advances in optics, camera production, developing, and imaging have had an effect on the way people view images. Prior to the 1970s, most people in the United States used slide or chrome film and viewed the images with a slide projector. After that, people began to make prints from color negatives. The simultaneous increased use of the Internet and email, relatively cheap computers and digital cameras were seen in the early part of the 21st century, the dominant method of viewing still images has been on computers and, to a lesser extent, on cellular phones (although people still make and look at prints). These factors have led to a dramatic decrease in film and film camera sales and film processing and has had a dramatic effect on companies such as Fuji, Kodak, and Agfa. It is unknown whether film will continue to be purchased on the scale it has been for most of the 20th century, if it will disappear altogether, or if it will be something used by a dedicated few.
