Just some of the headlines from the July 21, 1969 NYT, Bowdlerized and Grangerized, the "negative space" of headline news.
Hitchcock is quoted as saying "Drama is life with the dull parts cut out of it." This is the inversion of that idea, with the important parts removed so that they can later be implied, similar to Rachel Whiteread's negative space above books.
Headline news creates a negative space of information "below the fold", that sits in the shadow (or IS the shadow) of where our attention is directed, yet can actually be our own positive space. But even then, daily news without some type of headline, creates its own vacuum: If there were no major headlines you'd wonder where they were. All questions of attention (at least in the arts) lead back to John Cage, who was the great director of consciousness below the fold.
July 21, 1969 obviously was a very important headline day, but by removing the headlines and only including the fluff and the text "21" (from the leader on the microfiche tape), the event is implied and provides an ambiguous subtext about what has happened since that point, specifically the conspiracy theories about whether the mission was completely staged. In the "shadow" of that is a bricolage of Rich Little, TV listings, classifieds, advertisements, and so on.
An exposed line of text at the very top, emerges from the glare of banality: "Mr. Armstrong was clearly seen descending the ladder from the LM module, and...I Switched to WHN News"
Something important and interesting can be suggested by the banal, or that which remains after being expurgated. For example in the "edit wars" on Wikipedia, what often remains is the battle line between what is substantive and what is trivial.
