Lindenstraße (literally " Lime Street") is a German television drama series, broadcast by Das Erste. The first episode aired on 8 December 1985 and since then new episodes have aired weekly. Its current timeslot on Das Erste is Sundays at 18:50. The events of the Sunday episode usually take place on the Thursday before the show, based on the TV station's original plan of airing the episodes Thursday night. Prior of the start of the show, the timeslot was switched to Sunday evening but the Thursday remained the day the events usually take place as the show shall feature the daily life routine of the protagonists on a working day. Exceptions are the so-called holiday episodes that take place on Sunday, such as for Christmas and Easter and also on important election days (especially the election to the German Bundestag).
Setting the pace for other soap operas in Germany, the first episodes were met with mostly bad reviews. However, Lindenstraße soon became one of the most successful shows on German TV.
