I recall when NBC aired the 30th Anniversary College Bowl Special in 1984, Pat Sajak was reading a question about the VCR business, and mentioned he was recording the special on his home recorder.
The question dealt with two motion picture studios suing a VCR manufacturer in 1976, arguing that it violated copyright laws. The question asked:
Which manufacturer was sued? Answer:Sony (for its Betamax)
Then, what two studios filed the suit? Answer:Walt Disney and Universal Studios
