Nearly 31 million viewers watched live U.S. television coverage of Donald Trump’s presidential inauguration, far fewer than tuned in to Barack Obama’s first swearing-in, but otherwise the biggest such audience since Ronald Reagan entered office, ratings firm Nielsen reported on Saturday. The tally for Trump – 30.6 million viewers on 12 broadcast and cable networks that aired live coverage from about 10 a.m. to 6 p.m. EST – surpassed the TV audiences measured for his two most recent Republican predecessors – both inaugurations of George W. Bush and the one of his father, George H.W. Bush.
