Virtually the entire runs of the corporation's pre-1970s soap operas have been lost. In the 1950s and 1960s, the BBC soap operas "The Appleyards", "The Grove Family", "Compact", "The Newcomers", "199 Park Lane", and "United!" produced approximately 1,200 episodes altogether. There are no episodes of either "United!" or "199 Park Lane" in the archives, while only one episode of "The Appleyards", three episodes of "The Grove Family", and four episodes each of "Compact" and "The Newcomers" are known to exist. Three episodes of "Dad's Army" are missing, all from the second series.
