'MythBusters' Drops Kari, Grant and Tory

Discovery Channel's lone remaining science series, MythBusters, has lost 60% of its cast. The show announced Thursday night that that episode would be the last to feature Kari Byron, Tory Belleci and Grant Imahara.

MythBusters started out with just the two main cast members, Adam Savage and Jamie Hyneman, special effects gurus who used their science knowledge and engineering chops to test common pop culture myths. The show was fine in those early days, but MythBusters really took off when it grew to the current cast. The trio joined the full cast of MythBusters 10 years ago.  They brought a new chemistry to the show, and Byron brought a little nerd sex appeal too.

Now the era of five hosts busting multiple myths per show is over. And it sounds like money is at the root.

"I guess you guys are finding out the news right about now. After a decade of theMythBusters, we are no longer with the show," Kari said in a series of tweets. "Thank you to all the fans who have supported us. 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 @MythBusters. I am sad for an ending but there will be exciting new adventures for us."

Chances are, budget cuts are to blame. Discovery Channel has all but dropped science programming in favor of reality shows about gold and cars, bogus documentaries about sharks, along with its survival hit Naked and Afraid. The reduced MythBusters probably isn't going to last long now.
