Mike and his son Chris have both been in different places, different times asking different questions of different people.
Mike Wallace started out in the 1930’s as a radio announcer in Detroit, later Washington DC.
In the 1950’s his late night “Nightbeat” interview series ran on Channel 5 in New York. Wallace gave a late news roundup and interviewed a guest.
ABC-TV liked the show and brought Mike Wallace to the network with the “Mike Wallace Interview” series on weekends.
It was in the early 1960’s that Wallace made it to CBS and eventually found his way to producer Don Hewitt’s creation called “60 Minutes” where the Mike Wallace ambush interview became the stuff of legend.
In other words, they are weasels that blow with the wind.
