So they just announced MythBusters is done after this season. After a good long run, Jamie and Adam are gonna move on to other projects.
What happens to Tested?
I imagine Berman Braun only cares about "Jamie and Adam's Tested" and would try to offload it to somebody else or just shut it down if there isn't somebody immediately ready to take it off their hands. Again for clarification, they have not actually said MythBusters is ending but as they enter their eleventh season I can easily see them calling it a day within the next five years.
