NBC picks up Law & Order: SVU for Season 20, renews Dick Wolf's three Chicago series

Variety

Wolf's four NBC shows will all return next season -- Chicago Fire for Season 7, Chicago P.D. for Season 6 and Chicago Med for Season 4. Additionally, Wolf's Law & Order franchise will carry on with SVU reaching Season 20. SVU is still one of NBC highest-rated shows, averaging just under six million viewers. The oldest Chicago series, Chicago Fire, is currently the lowest-rated of the Chicago franchise, according to Variety. But it still performs solidly with just under six million viewers. The newest Chicago show, Chicago Med, is the highest-rated of the franchise, averaging 6.7 million viewers. In response to the SVU pickup, Ice-T tweeted: "FYI: SVU has OFFICIALLY been picked up for Season #20 Run and tell that!"
