Maybe then you should tell the knowledgeable people of the BBC Education website that they are wrong then?http://www.bbc.co.uk/dna/h2g2/A790175"Possessive Adjectives and PronounsThese are technical terms for two very common groups of words. The first group, is your, her, his, its and their. Notice the complete lack of apostrophes - the ball belonging to it is signified as its ball. And 'his' is not 'he's'. The corresponding possessive pronouns all end in s, with, once again, not an apostrophe in sight: yours, hers, his, its and theirs.There is perhaps understandable confusion between the 'its' here with the contraction of 'it is' - it's. This is somewhat contradictory but helps to show that there is a difference in meaning between it is and that which belongs to it. This rule is frequently overlooked. Don't be a statistic.PluralsEXCEPTING THE ONE CASE ABOVE, THERE IS NO NEED TO USE ANY APOSTROPJE WITH PLURALS.There seems to be some primordial urge in writers of shop signs to use it to denote plurals. This is manifestly wrong. CD's: The plural of CD is, by convention, CDs. Alternatively, CD's may be used too, though this is not at all recommended. This applies to all other abbreviations like HGVs or A to Zs. Capisce?1000's: If by some gruesome mischance you feel you need to butcher the beauty of our language by telling us you have lots of things on offer in, say, your Poundsaver store, please have the decency to write 1000s. Especially if you have 1000s of CDsThe 70's: The 70's are in fact the '70s. And don't you forget it!Pencil's: That means belonging to the pencil, not more than one pencil."
