Internet Archive Television News Archive Founder Roger Macdonald pointed out the fascinating finding that the words "terror" and "terrorist" are used very differently in chyrons and captioning. The two words are used nearly equal amounts in closed captioning with the same breakdown across stations, but when it comes to chyron airtime, "terror" is mentioned as much as 10 times more often, with CNN strongly preferring "terror" and Fox News strongly preferring "terrorist".
In the spoken word dialog of closed captioning, "terror" appears nearly equally on BBC and Fox News and less frequently on CNN and MSNBC (Y Axis is number of 15 second clips mentioning the word at least once).
The word "terrorist" appears at relatively the same rate and with relatively the same breakdown across stations (Y Axis is number of 15 second clips mentioning the word at least once).
In terms of chyron airtime, Fox News mentioned "terrorist" far more often than the other three stations (Y Axis is the total seconds of airtime in which the word appeared in the onscreen chyron text).
Compare that graph to the one below, showing chyron airtime devoted to "terror" (Y Axis is the total seconds of airtime in which the word appeared in the onscreen chyron text).
Unlike closed captioning, where the two terms appeared relatively equally and with the same station breakdown, here the total airtime is as much as 10x greater for "terror" than "terrorist". Even more interestingly, while Fox News used "terrorist" almost twice as often as CNN, CNN actually used "terror" 1.2 times more than Fox News.
We're excited to see what you're able to do with these new capabilities!
