“About 36.6 million Americans watched President Trump live on television on Tuesday night, tuning in for his 100-minute speech to a joint session of Congress — the longest of its kind in the modern era.
Nielsen, the ratings agency, said the live television audience for Mr. Trump’s wide-ranging and often pugilistic address was up 13 percent from former President Joseph R. Biden Jr.’s
final State of the Union speech a year ago.
… According to Nielsen, about 71 percent of live TV viewers were 55 and older. …”
The annual presidential speech is one of the last remaining mass-audience media moments available to a national politician.
