Order of release was essentially:
Fate/Zero LN
Fate/complete material IV (which had the prototype designs for Fate/Apocrypha)
Fate/Zero anime
Fate/Apocrpha LN
Fate/Apocrypha anime

The Fate/Zero anime is what caused the fandom to explode, resulting in a bunch of fanart being made for the characters in Complete Material IV who might otherwise have never actually seen the light of day.
