LOS ANGELES • Charlie Sheen's Two And A Half Men character was run over by a bus and got a full-scale funeral.
Glee actor Corey Monteith died in real life and had a tribute episode. House Of Cards will return minus scandal-tainted Kevin Spacey, with his screen wife taking centre stage.
Whether by death, design or disputes, television shows are adept at losing or killing off key characters and carrying on without them.
ABC television's announcement last Thursday that it had ordered a spin-off of cancelled hit comedy Roseanne, without star Roseanne Barr, is the latest in a long history of abrupt changes of direction on the small screen.
ABC did not say how it would deal with Roseanne's character in the new show The Conners, but audiences in the past have had little problem accepting sudden or dramatic changes.
"If you lose a main character or someone walks out or there is a controversy, and the fix means it is still a funny or compelling show, then most people will forget very quickly," said Mr Robert Thompson, professor of pop culture at Syracuse University.
Sometimes, actors wish to leave. On other occasions, they are fired because of scandals or disputes.
In some cases, actors die in real life or their characters are written out of long-running television shows to create dramatic tension.
If they are lucky, they are fictionally dispatched to a far-off city or a new job, like George Clooney's exit from ER in 1999, when the actor wanted to develop a movie career.
Others, such as Sheen, fired in 2011 from what was then the most-watched comedy on American television after months of drink and drug-fuelled partying, are dealt a grisly screen ending.
Characters whose names also provide the title of a show, such as Roseanne, are not immune to being disposed of.
Valerie Harper, the star of Valerie, was fired in 1987 after a pay dispute. The comedy continued without her for three more seasons, although it underwent two changes of name - Valerie's Family and, later, The Hogan Family.
In the coming months, two award-winning shows - Netflix political drama House Of Cards and Amazon's transgender show Transparent - will return without lead actors Kevin Spacey and Jeffrey Tambor, who were both dropped because of sexual misconduct allegations.
Neither show has detailed how it will dispatch its main character. Spacey, who is accused of sexual misconduct by more than 20 men, has said nothing since an apology to the first accuser in October last year. Tambor has denied any wrongdoing.
There is no guaranteed recipe for success after the departure of a major character, although Mr Thompson said retaining viewers was more likely when a show had a strong ensemble cast already in place, like the 1980s comedy Cheers.
"This is show business, not science. You do it and see how it works," said Mr Thompson.
Steve Carell's requested departure from The Office in 2011, when his character moved to another state, brought a ratings slump and the comedy was cancelled two years later.
8 Simple Rules For Dating My Daughter changed abruptly from comedy to a tragedy when its star John Ritter died suddenly in 2003 and the death of his screen character became a major plot point.
Sometimes, imagination is all it takes. The original series of Roseanne ended in 1997, with Dan Conner (John Goodman) dying of a heart attack. Dan was alive and well when the series returned later and what happened was dismissed as fiction, and the show moved seamlessly on.
