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.
Griffeth has also written three books to date, two on finances: Bill Griffeth's Ten Steps to Financial Prosperity (Warner Books), which was published in 1994, and The Mutual Fund Masters (McGraw-Hill), which was published in 1995. Both books were Fortune Book Club main selections. His third book is "By Faith Alone: One Family's Epic Journey Through American Protestantism" (Random House), which was published in 2007 and deals with his family history.
Along with his co-anchor Sue Herera, Griffeth received his Bachelor's Degree in Journalism in 1980 from California State University, Northridge. In 2000, CSUN honored him with its Distinguished Alumnus Award.
