The cine plus Online Editorial Office in Erfurt is responsible for the www.lexi-tv.de portal. It works in tandem with the television programme LexiTV shown on the regional MDR channel, researches current and historical knowledge and presents it as top-quality journalistic texts. Films produced for LexiTV, classified by subject, can be retrieved at www.lexi-tv.de.

As the library of texts, films and pictures grows, the various dossiers develop into higher-level editorial 'topic worlds'. At www.lexi-tv.de, all viewers – whether they are school kids or teachers, whether they are interested in technology, art or history – can reinforce the knowledge they have acquired during the television programme and pick up interesting additional information. In 2003, the knowledge portal won the Grimme Online Award. www.lexi-tv.de is a co-production by MDR and cine plus and is funded by the Mitteldeutsche Medienförderung (East German Office for Media Funding). The Erfurt-based Editorial Office also offers other interested parties its many years of experience in content production.
