Yup, they peer at local internet exchanges (e.g. LINX in London - www.linx.net / INEX in Ireland - www.inex.ie), cache locally where they can (uk.youtube.com / ie.youtube.com are what you get redirected to periodically over here) and I would imagine that this drastically reduces their "internet" bandwidth consumption.

It must be cheaper for them to cache popular content within the ISP system and send it out that way.
