The Nielsen company said 36 million people watched Sunday night's coverage, the biggest audience for the second night of a non-U.S. summer Olympics competition since TV began covering them in 1960. Counting the opening ceremonies on Friday, an average of 35.8 million people have tuned in for the three nights, well above the 30.6 million who watched the first three nights in Beijing in 2008 and considerably more than the 24 million who saw the first three nights of the Athens games of 2004.
