Jim Lehrer announced on Thursday morning he's leaving the anchor desk of PBS' nightly 'NewsHour' program after a record 36 years at the helm, according to the show's blog and The Washington Post.

The 76-year-old journalist said June 6 would be his last day, but that he would continue returning to the show on Fridays to host a news panel. He is the longest serving news anchor in TV history.

"I have been laboring in the glories of daily journalism for 52 years ... 36 of them here at the NewsHour and its earlier incarnations," he told his staff. "There comes a time to step aside from the daily process, and that time has arrived."

Lehrer teamed up with Robert MacNeil in 1975 to create 'The MacNeil/Lehrer Report,' a half-hour news program that 8 years later became 'The MacNeil/Lehrer NewsHour.' In 1995, MacNeil departed and it became Lehrer's show to run.
