Does anyone remember eating Cheez-Whiz from 50+ years ago?

Back in the stone age, way back… before cars had seatbelts, and men walked on the moon, my parents used to buy and serve us Cheez Whiz. It came in a tall, slightly tapered glass jar. When my dad would open it there would be a loud pop as the vacuum seal was broken. There was always a layer of popped bubbles on the the top surface so you knew it was untouched.
It was quite thick and difficult to spread but it was worth the effort.

I had not eaten any in ages and recently bought some Cheez Whiz on a lark. I was disappointed to see it was different from how i remembered it. The jar was a squat cylinder and it was labeled Cheez Whiz Original Cheese Dip. It was suspiciously easy to spread.

Do you remember the good stuff? I’ll admit to using the term loosely. Did I buy the wrong product? Does the real thing even exist or has it gone the way of the Dodo bird and real M-80s and cherry bombs?
Did you eat it?
