‘That 70’s show’ clearly has an episode where the Intellivision II CIB was shown on the shelf of a store. Don’t know what season/episode.
’National Lampoon’s Vacation’ actually had an Intellivision sound (don’t recall) when Clark was planning the Wally World trip.
’Grandma’s Boy’ a movie by Adam Sandler has a TON of Intellivision representation from Frog Bog challenge scene, to running man poster I believe, & approx. 12 or so CIB games surrounding the main character’s cubicle.
