I have said on other threads that when I was in Chicago last October, two weeks before Britain could have crashed out of the EU, the main news channel LED on Harry and Megan and the "crisis" at the palace. I had no idea what they were talking about but this story was what they thought was more important than any US issue as well. It was incredible.
Yes, local news features car crashes and other non essential items, as well as elections, local and national politics, police shenanigans, business and sports and weather reports.
Maybe the crashing out of the EU wasn't featured because Chicago wasn't crashing out of the EU? And maybe the UK in general isn't all that important to Chicago or even to the US? Shock, horror, the UK isn't as important in the US as it thinks it is.
But its well known celebrities are recognisable enough to boost ratings.
There are outlets other than the local broadcast news stations though. Chicago's PBS station, WTTW ('Window To The World'), broadcasts exceptional local, regional and international coverage and analysis. It has been around since 1955. It is affiliated with a truly incredible classical music station, WFMT, which broadcasts worldwide thanks to the wizardry of newfangled technology.
