Jerry Seinfeld is heading back to the coffee shop in his digital series "Comedians in Cars Getting Coffee." The show, which features Seinfeld and other high-profile comedians, will be airing four more seasons.

The show, which began in 2012, has been viewed over 40 million times online and has earned an Emmy nomination for outstanding special class -- short format nonfiction program.

Jason Alexander, Alec Baldwin, Todd Barry, Mel Brooks, Louis CK, Larry David, Tina Fey, Michael Richards and many more have already appeared on the show.

"Comedians" features Seinfeld driving vintage sports cars on his way to pick up comedians. He then takes them to a coffee shop where they have a conversation. The episodes last anywhere from seven to 25 minutes.

Seinfeld, who serves as the executive producer, turned 60 on April 29. He is best known for his sitcom "Seinfeld," which lasted nine seasons. After "Seinfeld" ended, Seinfeld chose to go back to stand-up comedy instead of trying to continue his television career.

Seinfeld, like Jay Leno, loves collecting cars, and he shows that in each episode of "Comedians in Cars Getting Coffee" by showcasing a different car each time.

In the very first episode of "Comedians in Cars Getting Coffee" Seinfeld picks up Larry David, "Seinfeld's" co-creator, in a 1952 Volkswagen Beetle.

In another episode, Seinfeld and former another "Seinfeld" co-star, Jason Alexander, head to the same coffee shop they spent so much time at on "Seinfeld" to talk about the Super Bowl being held in New York.

The show's fourth season will begin early this summer and will feature six episodes.

The show received a good review from Mike Hale of the New York Times. Hale said the show's "editing and filiming are, if you break them down, impressively complex and artful for a Web series."

Seinfeld has been listed by Forbes as the highest-earning comedian of 2013.
