Question: Hi, Jeff. Who was America's first female game show host? — Todd G., Fayetteville, Ark.
Televisionary: First things first, Todd. Who the heck is Jeff?
Moving on: America's first female game show host was Arlene Francis. The late Ms. Francis, probably best known for her What's My Line? days, handled the hosting duties on Blind Date, which debuted in 1949. There weren't many other lady hosts for decades until Betty White and Just Men! in the early '80s.
Now, your next question may well be: Why so few? In that case, as Anne Robinson would say, I am the weakest link. I can't tell you.
