Today it's a double-whammy of Chicago-based TV shows, as Chicago Fire returns for a third season and spin-off show Chicago P.D. is back for its sophomore season.
In the season three opener of Chicago Fire we'll find out who from Firehouse 51 survived the cliffhanger explosion at the end of last season, whilst 'Voight', 'Lindsay' and the whole District 21 team are back breaking the rules to uphold the law in Chicago P.D.
The billboards for these returning NBC dramas were photographed in multiple locations along La Cienega Boulevard and Sunset Boulevard from August 26 to September 6, 2014.
So we've had dramas based on firefighters, paramedics and the police, so the question now must be what's next, will we see a Chicago M.D. or Chicago Legal anytime soon to expand this televisual universe.
