Jan and Ron: It was only 24/7 for the first couple of days, not any more. The ‘exact event’ is still broadcast e.g. the cavalcade from Northolt to Buckingham Palace, the procession from the Palace to Westminster Hall etc and then rerun in bits throughout the day in news bulletins for those who missed the event live at night. Normal broadcasting has resumed otherwise.
I could say the same about sport which also takes over ALL channels most weekends of the year, not just a few days once in 70 years.
