Man has used information storage and transferring media – the carriers, since pre-historic times. Along with the development of carriers, big changes in the quality of public, cultural, political life take place. The industrial or technological revolution of 19th century makes an overturn in the area of information carriers: the photograph, telegram, film, radio and telephone are invented. The information carriers of 20th century develop in a faster pace: the invention of computer, creation of networks change the world… every day.
