NCIS commercial

Did anyone else see the NCIS commercial last night for the epp airing tonight?  It announces that there will be a "crossover" episode between NCIS and NCIS:LA.  It totally made me laugh out loud, because "crossover" isn't used in the tv business, is it?  As far as I knew, that was a fannish term, and it amused the hell out of me to see it being used on TV.
