News clips from the USA are often 4:3 – why?  Is it a technologically backward country, or do they only export their news in a universal format?  I see work-arounds to disguise this fact, like framing the whole clip in a themed border, or widening the clip by tacking onto the pillar-box sides a blurred-out duplicate of the clip that’s been zoomed, stretched or clipped.

And while I’m noting this, why is it that the watermark on these clips is almost universally blurred out and overlayed with the local broadcaster’s watermark – can’t they get the raw, unwatermarked footage from the provider?
