“The Office” and “30 Rock,” two of NBC’s most popular sitcoms, have just begun their final seasons.

Both shows have become extremely popular among viewers, many of whom are teenagers.

The ninth season of “The Office” began Sept. 20, and is scheduled to last 22 episodes. “30 Rock” was renewed to have a shortened, seventh season of 13 episodes.

Combined, the two comedies have won 25 Emmy Awards and Golden Globes over the years.

“30 Rock” began its first season in 2006, and is about Liz Lemon (Tina Fey) who is the head writer of a comedy show called “TGS with Tracy Jordan.”

She must deal with an arrogant new boss, Jack Donaghy (Alec Baldwin), and a crazy new star, Jenna Maroney (Jane Krakowski).

For me, “30 Rock” became uninteresting after the fourth season. After that point, I found the humor to be less in quantity and more in quality. I didn’t like when Kabletown bought NBC on the show, which I later realized to be a satirical reference to the purchase, at the time, of NBC Universal by cable company Comcast.

“The Office” began in 2005, and was essentially an American remake of a popular BBC series consequently named “The Office,” which first aired in 2001.

The show is about the quirky employees of Dunder-Mifflin Paper Company and their manager, Michael Scott (Steve Carell).

“The Office” has always been my favorite comedy because of the humor each character adds and the genius use of innuendos, especially Scott’s famous “That’s what she said!” jokes.

Despite my many fond memories of  “The Office,” the eighth and ninth seasons have been unnecessary and are bringing down the show’s once -high standards.

At the end of season seven, Carell left the show that made him famous, depriving fans of the “World’s Best Boss.”

Since his absence, “The Office” has become a cluster of new bosses and characters, many of whom are rather odd fits for the show.

But none of these things can discourage me from spending 30 minutes every Thursday night to watch this great television series.

Both “30 Rock” and “The Office” have brought joy and humor to their viewers, and have really set a stage for the standard of good comedy.

Losing these shows will be a terrible loss for NBC, but I hope the network has some good ideas for what comedies come next.

And to anybody who thinks these shows won’t be missed, I have one thing to say: FALSE! They will be missed dearly.
