with Brockhaus In April 2004, a complete list of article titles from the leading German encyclopedia Brockhaus was uploaded to the German Wikipedia, in an apparent attempt to facilitate the creation of still missing articles. A representative of Brockhaus asked for and obtained the deletion of what was believed to be a copyright infringement. As a result of the developing email conversation, a group of five Wikipedians visited the "new media" group of Brockhaus in Mannheim on 1 July 2004. The friendly meeting saw a lively discussion of the differing approaches to writing an encyclopedia; it became clear that Brockhaus had closely observed Wikipedia for quite some time. Subsidies from the German government In June 2007, a project on renewable resources (WikiProjekt Nachwachsende Rohstoffe) was initiated, the goal being to write and improve articles on the topic. The project was run for three years and was subsidized by the German Ministry of Agriculture with approximately €80,000 a year. It was organised and managed by the private company "nova-Institut GmbH". Nova GmbH and Wikimedia Deutschland e. V. fund the project with approximately €60,000 a year in addition, so the budget is approximately €420,000 in total. These funds were mainly used to organise the project and also to search for experts in the field who have not contributed to Wikipedia yet. Nova may also have paid expense allowances to authors. Most-disputed articles According to a 2013 Oxford University study, the article on Croatia was the most disputed article on the German Wikipedia. The top ten most disputed articles then also included Adolf Hitler, Scientology, and Rudolf Steiner. One of the largest disputes about simple sentences, however, concerned the Donauturm in Vienna. Whilst the observation tower shares some architectural aspects with the Fernsehturm Stuttgart, it was never planned for TV broadcasting purposes. The German Wikipedia had a rather lengthy (about 600,000 characters) discussion about the suitable title and categories, inasmuch as numerous Austrian authors denied the description of Donauturm as a "TV tower". The Spiegel coverage of the issue cited a participant with "On good days, Wikipedia is better than any TV soap". Reviews and research In September 2004, the computer magazine c't compared the German Wikipedia with the Brockhaus Multimedia encyclopedia and the German edition of Microsoft's Encarta. On a scale from 0 to 5, Wikipedia ranked first with a score of 3.4. A few weeks later, the weekly newspaper Die Zeit
