This finding is becoming less important by the year. It’s been quite a while since you could easily buy an HD TV - they’re all 4K, even the small ones.

I first heard it in pronounced “jif” from a guy in my college dorm in the mid 90s. I’ve just pronounced it that way every since. Is it there a generation gap in how it’s pronounced? I do catch some flak from my kids about how I pronounce it.
