Although German companies have their fair world market share in producing for this niche market, the major percentage is sold into export. MindGeek's age-verification software AgeID, which is used to verify the ages of users of pornographic Internet websites, has been in use in Germany since 2015. The world's first sex shop was opened in Flensburg in 1962 by Beate Uhse AG. Post-WW2 commercial movie pornography German began with the softcore film "Graf Porno und seine Mädchen" (Count Porno and his girls) in 1968. The movie's success (more than 3 million admissions) lead to a whole series of films that was and is referred to in German media as the "Sex-Welle" (sex wave). The most well known film of this period is "Schulmädchen-Report: Was Eltern nicht für möglich halten" (The School-Girl Report, what the parents don't believe possible) by Ernst Hofbauer in 1970. The sex scenes had become bolder with time and by 1975, when the legal ban of pornography was lifted, the era of German hardcore pornography began. Director Hans Billian was the protagonist of the period and the films were usually in line with the so-called "Bavarian porn sex comedies", often depicting male performers as comic characters, like Sepp Gneißl in "Kasimir der Kuckuckskleber" (1977). This era was also characterised by several Josephine Mutzenbacher films. Vela Supercluster  The Vela Supercluster (Vela SCl, VSCL) is a massive galactic supercluster about 265.5 megaparsecs (870 million light-years) away within the vicinity of the Zone of Avoidance, centered on the constellation Vela. It is one of the largest structures found in the universe; covering about 25 × 20 degrees of the sky. It consists of two walls: a broad main wall and a secondary merging wall. The combined dimensions of the walls are 115 km/s Mpc on the major dimensions and 90 km/s Mpc on the minor ones, which corresponds to about 385 million and 300 million light years, respectively. It is about 1,000 times the mass of the Milky Way galaxy, which corresponds to a mass of . About 20 initial galaxy clusters have been identified spectroscopically. The supercluster's discovery has been reported late December 2016 by Kraan-Korteweg "et al." through an analysis of the redshifts of 4 500 galaxies from the combined data of the 2dF Galaxy Redshift Survey which uses the AAOmega fiber optics from the Anglo-Australian Observatory (AAO), and the South African Large Telescope (SALT).
