The Birth and the Name Change

Puckett, a class act and a sportsman, did not forget the agreement. He personally reminded Costas of the wager. Honoring the public promise and the spirit of the game, Bob Costas legally changed his son’s birth certificate to include the middle name, resulting in the full name: Keith Michael Kirby Costas.

Stepping Out of the Shadow: Keith Costas' Own Emmy-Winning Career

While the name 'Kirby' may have opened a few doors, Keith Costas' longevity and success in the industry are entirely his own doing.

A Dedicated Production Professional
