The 13-episode orders means the two comedy series will share their timeslots with other programs, as they have done the past several seasons.

News about the future of “Parks and Rec” and “The Office”are imminent. Stay tuned.

Despite speculation to the contrary, NBC also just ordered a fourth season of “Parenthood,” even though it lost momentum when it took a six-week break this season, and it has a large (read, “pricey”) ensemble cast — maybe because it’s the youngest-skewing 10 p.m. drama on any broadcast network, and it refreshingly breaks the stranglehold that cops/docs/lawyers/desperate women have on the genre.

And, in addition to the already mentioned order for a new Dick Wolf drama series called “Chicago Fire” about fires in Chicago and the brave men and women who put them out, and the new JJ Abrams drama “The Revolution,” about people trying to reunite with family in a post-apocalyptic America where no technology is available because all forms of energy have ceased to exist, NBC just ordered a Jekyll & Hyde doc drama called “Do No Harm” — brilliant neurosurgeon with dangerous alter ego. On the slip side, NBC has ordered what sounds to be a super campy -rich-folks soap called “Infamous.”
