: Why is an advertisement often called a commercial? It also seems to be medium-specific - ie. the term is used with regard to TV, movie and radio, but I've never heard anyone say they saw it in a newspaper commercial.
Back when announcers announced, there were "commecial announcments" as opposed to news announcements, etc.
