Television lost a number of great TV shows in 2015, and HNGN remembers a few of the series that left a lasting impact on pop culture.

In the age of peak TV, the ending of one show seems to free up time to watch that show your friend keeps pestering you about. But we still mourn the loss of the shows that we welcomed into our homes for many years and aren't quite yet ready to let go.

"Two and a Half Men"

Charlie Sheen nearly torpedoed his CBS sitcom in 2011 when he publicly insulted the show's creator, Chuck Lorre, and tried to storm the Warner Bros. lot after the studio banned him. He was dismissed and the show wrapped season eight early, but it didn't give up on a ninth season.

Enter Ashton Kutcher, who came on the show as an Internet billionaire with a broken heart that buys Charlie's Malibu home and allows his brother Alan, played by Jon Cryer, to continue living in it. The show continued for four more seasons and ended by dropping Charlie's piano on a body double who looked very much like Sheen.

"Glee"

TV shows that revolve around song and dance numbers have rarely worked outside the variety format. But creator Ryan Murphy took a gamble, and it paid off big. The Fox musical launched live concert tours, and dozens of its cover songs made Billboard's Hot 100.

"Glee" suffered a major loss in 2013 when Cory Monteith died of a drug overdose shortly before the fifth season. His passing played out on screen as well, and Murphy announced a week after Montieth's tribute episode aired that the show would end after season six.

"America's Next Top Model"

Tyra Banks and beautiful people - a winning combination. The former Victoria's Secret supermodel launched the competition series for aspiring models in 2003. The show whisked away its contestant to exotic locations and made them all deliver the famous cosmetic slogan, "Easy, Breezy, Beautiful... Covergirl!"

"ANTM" was one of the few shows to make the transition from the UPN to The CW in 2006. It also helped launch the careers of Adrianne Curry and Yaya DaCosta.

"Parks and Recreation"

Amy Poehler led this little show that could, co-created by Greg Daniels and Michael Schur. For seven seasons, NBC jerked the comedy around across the schedule, but every year the show got better and gave us classic catchphrases like, "Treat yo self" and created the holiday "Galentine's Day."
