Overheard in the bathroom today... "Do you have a Playstation?" "A what?" "A Playstation." "Is that like an XBox?" "Yes" "No, I don't have one." Who knows what an XBox is, but doesn't know what a Playstation is? Score one for Microsoft.
Doesn't sound that improbable to me. He grew up in the age of Xbox 360 outselling PS3 in the US, so maybe his home was a 360-only home. Then they lost interest in video games entirely and never got any other console. So, "video games" = "XBox" only for him. Hypothetically.
