The timeline below shows the total seconds of airtime over the past two weeks in which Nagorno-Karabakh has been mentioned in the onscreen text of BBC News London, CNN, MSNBC and Fox News.

While this absence could be a result of different transliterations of the name, CNN appears to use the same transliteration.
The stark difference in attention can be seen in the graph below.
