When "That '70s Show" first aired, it made the punctuation mistake of putting the apostrophe between the 0 and the s, like this: 70's. Several seasons down the road, the show's producers realised their mistake and moved the apostrophe to its proper place, before the number 70: That '70s Show. This is correct because '70s is actually a truncation of 1970s.
Then comes along MediaCorp, doing its own copy of the show, right down to the punctuation error: 80's Rewind. For the record, it should be '80s Rewind. Let's see how many seasons it takes before they realise their mistake.
