One of the best ways to get a steady stream of income as an actor is to join a successful sitcom and have it syndicated. A show that has become syndicated allows actors to make a huge amount of money every year without having to find any other major acting jobs. Why do you think so many sitcom actors are either never seen again or don't appear in many projects afterward?

Sitcoms such as Friends, Frasier, and most recently Modern Family have become some of the more popular TV shows that have become syndicated over the years. They are often airing after five o'clock, perfect for when people come home from work or on as background noise while doing household chores. As viewers, we have created a massive income for these actors. Now they do not need to work again with all the royalties they receive from their past sitcoms. Here is a list of the top ten highest-earning sitcoms in syndication.

2 'Seinfeld' ($3 Million Per Episode)

One of the most successful sitcoms to hit our TV screens is the show about nothing, Seinfeld. The show was originally sold into syndication for $3 million per episode, according to Bezinga.com, but the viewership was so high it ended up earning so much more. In April 2013, Seinfeld had grossed $3 billion from syndication alone, amounting to roughly $17 million per episode.

1 'Friends' ($1 Billion Per Year)

Another successful sitcom that has developed a cult following in recent years is the 90's, hit Friends. According to Living.ALot.com, the series brings in approximately $1 billion in residuals each year. The former stars of the show receive around two percent in residuals meaning the cast makes roughly $20 million just from the syndication. Even though several cast members, such as Jennifer Aniston and Lisa Kudrow, continue to work in film and TV, it's safe to say they don't need to.

'The Big Bang Theory' ($1.5 Million Per Episode)

The Big Bang Theory was able to receive one of the biggest syndication deals of all time. The network TBS paid CBS $1.5 million per episode to get it syndicated on their network. Fox broadcast paid $500,000 for each episode. This brought them a total of $2 million per episode back in 2010. While it is unclear how much the cast makes per episode, Jim Parson, who played Sheldon Cooper on the series, brings in about $10 million a year in residuals.

'The Simpsons' ($1 Million Per Episode)

Most shows that become syndicated have usually stopped making episodes years before or will be ending the show shortly. Not The Simpsons; this show made its debut in 1989 and is currently in its thirty-second season. The Simpsons are currently in syndication on FXX and are making around $1 million an episode.

If it does, The Simpsons could earn more than $750 million, making it one of the biggest overall syndication deals.

'Everybody Loves Raymond' ($18 Million Per Year)

When Everybody Loves Raymond was airing on TV from 1996 to 2005, fans of the series could not get enough of it. The series received amazing reviews and top ratings during its time on air. After 15 years of the show being off the air, fans still watch the iconic series. Since the show has been syndicated on many networks, the actors on the show make a pretty penny in residuals. In fact, Ray Romano earns $18 million a year from the reruns.

'Fraiser' ($13 Million Per Year)

Frasier was on air for tens season on the network NBC from the early '90s to the early 2000s. While it is unknown how much the other networks have paid for the syndication of the show, Kelsey Grammer, the lead in the show, makes more than $13 million a year just in syndications and reruns.

'The Sopranos' ($200 Million Episode)

Just two years before The Sopranos ended its eight-year run, the popular drama series closed a $200 million syndication deal. The show ran on HBO for the eight years the series was on-air but later ran its re-runs on A&E as well, reported The Guardian.

'Modern Family' ($1.4 Million Per Episode)

The hit ABC sitcom Modern Family is one of the newer more popular sitcoms to hot syndication. Back in 2013, ABC made a syndication deal with USA Network, but the amount was never released, reports The Hollywood Reporter.

'Married…With Children' ($10 Million Per Year)

Married...with Children has aired its reruns on several different networks since it debuted on Fox in 1987. Ed O'Neil, who played the lead character, Al Bundy, makes around $10 million just in residuals. However, David Faustino, who played Bud in the series, said they "all got screwed over because Fox at the time was not a network." The show made billions of dollars, but the cast "didn’t really get a piece of that."

'Family Guy' ($1o Million Per Year)

Another long-running animation series that has become syndicated on many networks is Family Guy. The actors make a decent check and episode with Alex Borenstein, who voices Lois Griffen, makes around $225,000 for every new episode.
