Bizarre Copyright Date / Mistake

I noticed tonight that someone slipped up on the copyright at the end of the 2nd edition of I've Never Seen Star Wars.

At the end of the credits it read
© MMVIX

which I don't think is even vaild in Roman Numerals terms. The nearest you could guess at is eiter 2014 ( 2000, 5, 10-1 ).

It should be MMIX (2009).

I have seen that mistake more than once this year. I think it was on the first couple of Hollyoaks this year as well
