Origin of Superman early issues of the series, it was unclear if the story was intended to be the new origin of the mainstream Superman or the beginnings of a new universe, similar to Marvel's Ultimate line. DC later confirmed that "Birthright" was the new official origin of Superman, and it was embedded into the Superman fiction in "Superman" (vol. 2) #200.

Superman hope. Clark works as a newspaper journalist. In the earliest stories, he worked for "The Daily Star", but the second episode of the radio serial changed this to the "Daily Planet". In comics from the early 1970s, Clark worked as a television journalist (an attempt to modernize the character). However, for the 1978 movie, the producers chose to make Clark a newspaper journalist again because that was how most of the public thought of him. The first story in which Superman dies was published in "Superman" #149 (1961), in which he is murdered by Lex Luthor by means of kryptonite.
