Mayim Bialik announced Friday that she is stepping down as host of "Jeopardy!"

In a post on social media, the star of "The Big Bang Theory" shared the news, stating: "I have some Jeopardy! news. Sony has informed me that I will no longer be hosting the syndicated version of Jeopardy!"

The 48-year-old Bialik did not provide further details about the reasons behind her departure. However, she expressed gratitude for being nominated for an Emmy this year for outstanding host of a game show and expressed her appreciation for being part of the Jeopardy! family.

CBS News has reached out to Sony Pictures Television, the producer of "Jeopardy!," for comment but has not received a response yet.

In July 2022, Sony named both Bialik and Ken Jennings, the most successful contestant in "Jeopardy!" history, as the permanent hosts of the show, with the two sharing hosting duties. 

The two had been among several guest hosts who had filled in on a rotating basis following the death of longtime host Alex Trebek from cancer in 2020.

Jeopardy! Upheaval

In August 2021, the popular game show "Jeopardy!" experienced significant turmoil. The show's then-executive producer, Mike Richards, was initially announced as a permanent host alongside Bialik. However, Richards decided to step down just a week later due to the emergence of past inappropriate comments he had made online.

Additionally, in May, Bialik made the decision to stand in solidarity with the Hollywood writer's strike and chose not to host the final week of season 39 of "Jeopardy!".
