Prior to joining CNBC, Griffeth was part of the production team that started the Financial News Network in 1981. During his 10 years there he was nominated for a CableACE award as best news anchor for his work anchoring FNN's coverage of the 1987 stock market crash.

Griffeth joined CNBC in 1991, when NBC purchased FNN and merged it with CNBC. He has anchored a number of programs for CNBC, including Power Lunch (Monday-Friday, 12-2pm ET), which he co-anchored with Sue Herera. He garnered 6 more CableACE nominations along the way.

On November 19, 2009, CNBC president Mark Hoffman announced in an email to the staff that Griffeth would be taking a one-year leave of absence from the cable channel. His last day, at least for the next year, was Wednesday, November 25.
