/**
 * How long it runs, offered as lengths that say what they are for.
 *
 * Every option was "14 days", which tells a media buyer everything and a
 * first-time advertiser nothing: the question is not how many days but what
 * each length is for, and that is the difference between picking one and
 * guessing one.
 *
 * Two lengths have a well understood purpose and now carry it. The rest stay
 * as plain lengths rather than being given invented names, and none were
 * removed: naming three options is not a reason to take the others away.
