PhiCorp

PhiCorp was a company that produced painkillers without narcotic side effects.

History
In return for his protection, one of their representatives, Jilly Kitzinger, recruited Oswald Danes to speak in favour of allowing all drugs to be available without prescription. Rex Matheson theorised that this would increase their profit a hundred fold.

Jack Harkness, Gwen Cooper and Rex infiltrated a PhiCorp warehouse. They discovered a massive stockpile of drugs, leading them to believe the company had prior knowledge of Miracle Day. Jack said it was "bigger on the inside." (TV: Dead of Night)

Upon interrogating COO Stuart Owens, Jack Harkness learned that, while PhiCorp managed to profit off the Miracle, they were as much in the dark as anyone else. Owens had his own investigators trying to uncover the truth behind the Miracle, and how PhiCorp was being used in it, but the only investigator who had apparently learned anything chose to jump from a tall building.

Jack Harkness then found out the link between PhiCorp and The Blessing after realising the letter "Phi" in the PhiCorp logo represented the crack in the world between Buenos Aires and Shanghai that was The Blessing. (TV: The Gathering)
