Capitalization Profile of 293,590 Video Titles

The channels, the titles, the dates and the two ways of counting are on the shared page The Corpus and the Counting. In short: every title of every channel on the list between 1 January 2026 and 14 September 2026, uploads and live streams alike, repeats included, 293,590 titles from 274 channels, each read as published. A brand tag such as “| Fox News” stays in the title: it adds capitalized words that the Title Case test does not mind and a sentence-case title can carry, and a tag written in capitals (“| REUTERS”) is the channel's own label, exempt from the shouting test for that channel.

One rule sorts every title. Its tests run in the order below, and the first that fits decides; a word is a run of two or more letters, so numbers, initials and symbols are passed over, and a content word is any word but a function word (the, of, to, and the like).

Acronyms and labels. A word written in capitals because that is how it is written is not a shout. The acronyms are learned from the corpus itself: the 938 words that are all-capitals in at least four in five of their non-initial appearances in mixed-case titles (FBI, ICE, GOP, NATO, AI, CNN). The generic labels are a fixed list: LIVE, BREAKING, WATCH, NEW, FULL, EXCLUSIVE, UPDATE, REPLAY and the like. A channel's own tag words are exempt for that channel: the words of an edge segment it repeats on more than one title in twenty and at least twenty times, a “| REUTERS” suffix, a “GRAPHIC WARNING:” label, a show's name (84 channels, 315 words), so a tag written in capitals for a month is not a month of shouting. The exemption still cuts both ways: a name a channel always capitalizes can be learned as an acronym and stop counting, and a name written in capitals once, a show's or a product's, counts as a shout.

A channel's shares are over its own titles; channel-weighted averages them over the 274 channels and title-weighted pools the 293,590 titles (the two counts). The rankings of channels by a style's share or by diversity, and the counts of loud, quiet and single-style channels, are over the 258 channels with 30 or more titles.

A title's date is its publish time from YouTube's Data API, to the second; a live stream is dated by the moment it went live, and a Rumble title by its own listing. The series is drawn by month and by week (Monday to Sunday), each period counted the two ways the pies are, the channel-weighted mean over the channels with 15 or more titles in the month or 5 or more in the week, so a channel's two titles cannot swing it. A channel's range is the difference between its highest and lowest monthly share of titles with a shouted word (ALL CAPS and selective CAPS together), among its months of 15 or more titles, measured for the 177 channels with 6 or more such months; the eight with the widest range are the movers. Sep ends on the 14th, so its shares are over a partial month.

In every selective CAPS title, the shouted words are the ones the rule's own test found: three or more letters, written entirely in capitals, neither a learned acronym nor a generic label. A word counts once per title however often it recurs; a possessive or a quotation mark stuck to it is dropped, so TRUMP, TRUMP'S and “TRUMP” are one word, shown in the form it is written most. Its count is the number of titles that shout it; its rate is that count over the number of mixed-case titles (every title but the ALL CAPS and the short ones) in which the word appears in any casing, so a word always written in capitals rates 100%. The count ranking lists words that 5 or more channels have shouted; the rate ranking adds that the word appears in 300 or more titles. Each channel's own list, in the search, is its shouted words by count, those shouted in two or more of its titles.

• The rule is a rule. One shouted word makes a title selective CAPS, so light emphasis and a full-blown meltdown count the same, and the Title Case line is a threshold that a headline dense with proper nouns can cross.
• Small months are noisy. A channel with twenty titles in a month has a monthly share that can move ten points by chance alone, so part of every channel's range, and most of a small channel's, is sampling noise; the movers are the channels whose range is far too wide for that.
• The exemption is learned, so it leaks both ways. A show's name written in capitals on enough channels but not always ranks as a shouted word, and a name one channel always capitalizes is learned as an acronym and never counts.
