HISTORY OF ADVERTISING Bilboards and commercials on tv are modern inventions, but the idea of informing about a product and saying it's worth buying is very old. Archeologists have found advertisements in the form of papyrus posters and rock paintings. the oldest known ones are from 4000 BC. Advertsting changed with news technologies. In the 15th century thanks to the pronting press one could make many copies of an advertisiment ( now we get hunderts of leaflets by email every year). As europe suffered from many epidemics at the time, the most advertised products were medicines. Another change came in the 17th century with the growth of newspapers, but it was only in the 19th century that newspaper ads started to have not only slogaqns, but olso pictures and colours. The next stage were radio ads which appeared in the 20th century. At first there was one sponsor of a whole programme and the product was mentioned in it a couple of times. then radio stations started stelling time beetwen the programmes and commercials breaks were born. bardzo prosze o przetłumaczenie tego tekstu na dziś ;( bd nagroda ;D
