ITV put on short films and do Drama films, Entertainment and comedy. But ITV don't make allot of Short Dramas, because ITV doesn't get a big audience with Short Dramas and advertisers will not want to show the adverts to such a short audience. "We are looking for ideas of all shapes and sizes". ITV said this on their website

they even make a big title saying, "What we're looking for" They put this on their website so people and media producers can look on their website and see the title "What we're looking for". Then they will read it and help ITV. But first they put on "What we are" They how they make Big dramas such as 'Downton Abbey'.
