That compares to 19.4 million viewers from the previous evening, according to Nielsen.
The viewership also was less than the 22.8 million who watched the third night of the Democratic Convention last week. That evening, Kamala Harris delivered her acceptance speech and former President Barack Obama made remarks.
PREVIOUSLY: Republican National Convention TV viewership fell off significantly on its third night, which was highlighted by Vice President Mike Pence’s acceptance speech from Fort McHenry.
According to early numbers from Nielsen, an average of 15.7 million viewers watched in the 10 PM ET to 11:15 ET time frame across six networks. That compares to 18 million who watched in the same period on Tuesday, when First Lady Melania Trump spoke from the Rose Garden at the White House.
Last week, the Democratic National Convention’s third night drew 21.4 million across those six networks, during an hour that featured an acceptance speech from Kamala Harris and remarks from former President Barack Obama.
The third night TV viewership for the GOP convention also is off about 31% from the same day in 2016.
Fox News again led all networks, with 7.07 million viewers, followed by NBC with 2 million, ABC with 1.9 million, CBS with 1.78 million, CNN with 1.52 million and MSNBC with 1.48 million. In the 25-54 demographic, Fox News led with 1.38 million, followed by NBC with 595,000, ABC with 534,000, CBS with 497,000 and MSNBC with 311,000. The figures were released by Fox News. As they have on other nights this week, they racked up more viewers than the three broadcast networks combined and MSNBC and CNN combined.
Nielsen is expected to release additional data later on Thursday with viewership from additional networks.
The figures do not include viewership via streaming or other digital platforms.
