Several news sources, such as The Patriot-News in Harrisburg, Pennsylvania, have claimed that the total solar eclipse on August 21, 2017 is the "most-observed in history".
It was the most-observed and most-photographed eclipse in history, with many Americans staking out prime viewing spots and settling onto blankets and lawn chairs to watch, especially along the path of totality
The article states later that 200 million people were within a day's drive of the totality, and that it was primarily visible from the United States. Given that, I am skeptical about it being the "most-observed". Total solar eclipses have crossed India and China, each countries of one billion people, so I would have expected one of those, or another crossing a region more densely populated than the United States, to have been the most-observed total solar eclipse.
Was the August 21, 2017 solar eclipse indeed the most-observed in history?
