The five major television networks are rolling out their much-anticipated fall schedules - and a slew of new shows are on the way. Hollywood continues to get itself back on track after the Writer's Guild and Screen Actors Guild strikes sent production calendars into chaos. Many popular TV shows aired abbreviated seasons with fewer episodes.

Traditionally, May marks the end of the current television season, as most networks show reruns or special summer programming during a time that less people are indoors watching the tube. This week, the broadcast networks gathered advertisers in New York for the annual Upfronts - a chance to show off everything new coming up. But in with the new means out with the old, and many beloved shows have been unceremoniously canceled , much to the chagrin of fans.

Check out these shows that are no longer must-see TV. NCIS: Hawai'i was canceled by CBS in late April, leaving fans and its cast heartbroken. The news that Season 4 would not happen came just a month after the Season 3 finale was filmed.

Worse, the show was left on a cliffhanger that will likely never be resolved. No one thought the season finale would be its last episode, so fans were left with loose ends and the cast didn't get to say goodbye. Last week, several cast members reunited on a beach at sunset to be together one last time.

The group photo included Vanessa Lachey (who starred as Jane Tennant), Tori Anderson (Kate), Jason Antoon (Ernie), and his wife Seana Kofoed (Dr. Chase). .
