With Trumps 31 million viewers and 17 million who watched live streaming over the internet from CNN alone, he probably had 80 million viewers world wide with most being over the internet. But he had at least 50 million, which is way more than Obama's 37 mill.
Notice how the dishonest Trumpists compare Tramp's TV plus internet plus worldwide viewers to Obama's TV only, as if there were no internet or worldwide viewers for Obama. The GOP Senate's own inauguration historical data said that Obama had the highest viewership ever of the swearing-in ceremonies on the internet. So if liar Tramp actually had 80 million, Obama had 100 million.
Obama may have had a high mark for internet viewing at that time, but eight years later far more people are online and watching streamed programs than in Obamas day.
Comparing the two seems like a futile exercise, but if you have any numbers, lets see them.
