Possessive personal pronouns don't need the apostrophe. It's (apostrophe of omission) its.
Do not use an apostrophe in the possessive pronouns whose, ours, yours, his, hers, its, or theirs. Do not use an apostrophe in nouns that are plural but not possessive, such as CDs, 1000s, or 1960s.
This is primary school punctuation and usage. (At least it was once!)
Agreed, it's a crap thread Hing.
