In Australia our consumer protection laws have minimum warranty for most items (eg 3yrs or something for basic electronic products) but it scales with cost and quality.
It does not apply to everything as far as i know, but say you buy a $8,000 TV, you would likely get 5-6 years warranty because a TV of that cost should imply, to a reasonable consumer, it is of a quality that would be expected to last 5-6 years.
