A hat tip to Invidis of Germany for pointing out that the city of Frankfurt am Main has decided maintain a ban large displays in its streets, an approach that has upset some companies, such as Ep Communication GmbH of Cologne, which wanted to run a national campaign, but couldn’t do so. Frankfurt authorities are going out to get tenders for operating outdoor advertising in the city from 2018 to 2025. However, there is no tender for digital and a group of ten agencies has written an open letter to the authorities to complain about this.
