I have a Daewoo 15 inch portable cathode ray televison which I believe is 13 years old.
Although it sometimes gets swapped with a younger (7-8y/o) Beko of a similar design.
Or occasionally I will go downstairs where we have a 32" widescreen tv about 6 years old (it has a flat screen, but it is not a flat screen in that I think it is still CRT)
