This has occasionally happened, since UTV use the normally ITV1 Network Promotions Unit trailers as a base for their own trailers. Normally the voice track and the endboard is stripped out, as well as the ITV1 DOG
. However if an ITV.com (or in the past, itv.co.uk) text appears in the middle of the trailer, it has also appeared on the UTV trailer too.
In the case of the 'Monday's My Day' and 'Biography' strand, the endboards haven't been stripped out (although in the case of the former, the ITV1 logo was replaced by an oversized, out of proportion UTV logo, and the latter simply has a normal UTV logo). If the ITV.com appeared on these endboards it would appear on UTV too.
