So I checked a bit for the newspapers. None of the English newspapers I checked does it. In the USA, Wall Street Journal, NY Times, do it; but USA Today, LA Times, Chicago Sun-Times, Denver Post, Chicago Tribune don't. Washington Post apparently does or did both. None of the Australian newspapers I checked does it (and at first sight, most of them seem to fall in the following category...). Tabloids either use one foot high full capital titles, or don't capitalise. Not any French, Spanish, German use this capitalisation style either. Of course Germans do capitalise nouns, as they do in regular text. So, it seems to be an American-only thing, and not even widespread there (for newspaper titles).
