In the AdHistory, the advertising archive of the AdZyklopädie, there are more than two million adverts of the past 70 years. This includes, for example, the world’s oldest advert. This data enables us to learn more about the communication history of a company or a market segment. You can conduct a concerted search for certain spots and adverts of the past decades and, in the case of doubt, minimise the risk of accidental plagiarisms.
