I love this headline, from a purely linguistic standpoint. It's one of the best examples I've ever seen of an emerging phenomenon in the English language, wherein nouns are used attributively, like adjectives, forming chains. The example here, "US Health Tech Giant Change Healthcare", once we expand the abbreviation, reads as "Proper Adjective, Proper Noun, Common Noun, Common Noun, Common Noun, Proper Noun, Proper Noun", for a total of six nouns in a row, assuming we count "Change Healthcare" as two, which I think is fair. (An argument could be made that it's a single proper noun, or, alternatively, that "Healthcare" is a compound of two lexemes, both nouns. I split the difference and counted words as separated by spaces, which is customary for English-language text.)
Young people are probably going to look at that explanation and go "Yeah, so what?" But English didn't used to _do_ that. We used to have to use *way* more prepositions and adjectives. Not so many decades ago, it would have been written along the lines of "[Company], a large American company that produces technology for medical care, ..." Also, the name of the company would not have been Change Healthcare; something more like "National Medical Technology, Inc." would have been a far more likely name in the twentieth century.
I've been seeing this change building for a while, but it's nice to have a really good solid _long_ example that's not artificially contrived.
