Discovery's MythBusters is plotting a new direction.
As part of the shake-up, longtime investigators Kari Byron, Tory Belleci and Grant Imahara have exited the series, The Hollywood Reporter has confirmed.
"Kari, Tory and Grant have been an incredibly important part of MythBusters for over a decade," Discovery said in a statement. "From explosions to car crashes to even more explosions, this trio has helped shape MythBusters into the Emmy-nominated series it is today. Everyone at Discovery wants to thank them for their tireless work busting almost 1,000 myths, and we wish them all the best on their future endeavors."
Their departure was announced at the end of Thursday's episode, with Byron, Belleci and Imahara taking to Twitter to address the circumstances of their departure.
"It's been an amazing ride for 10 years! We couldn't have done it without you guys. You're the best fans anyone could wish for. Thank you," Belleci, who joined the show in 2004, wrote.
Said Byron, who also boarded in 2004, wrote: "After a decade of the Mythbusters, we are no longer with the show. Thank you to all the fans who have supported us." She added: "The show is taking a new direction. It was an amazing run. I learned so much about myself and the world. I love you all. I am sad for an ending but there will be exciting new adventures for us."
Co-hosts Adam Savage and Jamie Hyneman said the series will return to its "origins," with just the duo overseeing the show.
Noted Imahara, who joined in 2005: "Thanks @MythBusters for allowing us to teach science in a whole new way. Also, explosions. Now, on to the next adventure!"
Watch Savage and Hyneman make the announcement in the clip posted to Discovery's Twitter page.
MythBusters has been nominated five times for the outstanding reality program at the Primetime Emmys. It has yet to take home the trophy.
