NGAMENJITU RTP SLOT The series shares this concept with its former East German counterpart Polizeiruf 110, which is produced as four additional Tatort investigator teams aired under a different series name and opening credits by some regional broadcasters, primarily those that evolved from East German state television. Developed by the German public-service broadcasting organization ARD for their channel Das Erste, it is unique in its approach in that it is jointly produced by all of the organization's regional members as well as its partnering Austrian and Swiss national public-service broadcasters, whereby every regional station contributes several episodes to a common pool. While some (about 30) have been featured only once or twice, several investigators have featured in multiple episodes. Polizeiruf 110 shares the Sunday night prime time slot on Das Erste with Tatort.
