Many books, films and copyright documents still use Roman Numerals ??? The reason? There are no legal reasons ??? but Roman Numerals do look elegant, sophisticated, and tasteful.
A more practical reason though ??? is that they can be used as a little bit of trickery to hide the true age of something ??? As credits roll at the end a film, or you flip the first few pages of a book ??? MCMXCVI will probably just be glanced over by most people. How many individuals will actually bother to work out that film/book was made in 1996! So while it may be law to put the year something was made ??? Roman Numerals allow companies to hide dates in plain sight.
Use this page to find the true age of a book/movie/document or anything else that is showing a Year in Roman Numerals.
