Where were 8 track tapes made?

When I bought an 8-track player for my '79 Jeep CJ7, some of my friends made fun of me because they were all getting cassette players for their cars. Loved that Jeep. Loved that 8-track cranking out Jessi Coulter, Waylon Jennings and Willie Nelson.

It was the cassette tape that replaced the 8-track, and cassettes had a good long run until the CD took over.
