An even tougher question would ask on what day of the week was JFK's funeral.
I was 8 years old at the time (you do the math) and we were glued to the TV that entire weekend. I was watching NBC when Jack Ruby pumped a bullet into Oswald's abdomen live on national TV. The reporter was Tom Pettit. Then JFK's casket laid in state in the Capitol rotunda like forever, then there was a funeral procession which also took forever, all covered live on national TV.
Airchecks of the networks' live coverage can be found on YouTube, as well as the local Dallas station's coverage. They are all definitely worth watching.
AFAIK the first bulletin was read on the air by none other than Don Pardo who was on his shift at NBC at the time.
More OB game shows: the real mystery attached to the JFK assassination is the fate of Dorothy Kilgallen, who was covering the trial of Jack Ruby when she died. Somebody felt Dorothy had to be silenced. It's quite a coincidence that John Daly's father in law was Chief Justice Earl Warren of the Warren Commission. I'm sure Daly, who saw Dorothy every Sunday night, kept his father in law well informed about Dorothy's activities. Dorothy's homicide was never fully investigated.
