The Rio Olympics wrapped its first full week of competition on Friday night with more Michael Phelps, Katie Ledecky and a primetime kickoff for track-and-field.

Fast-affiliate ratings give NBC's primetime showing for the games, between 8 and 11 p.m., 23.9 million viewers and a 6.3 rating among adults 18-49. That's down from the night before and the lowest showing for a competitive night to date, but that's to be expected, given the lineup and Friday's status as a typically slower night for TV viewers. (The same Friday four years ago in London averaged 26.9 million viewers and an 8.1 rating in the key demo.)

Coverage also scored an overnight rating of a 15.9 among households, with a 28 share placing it in more than a quarter of all TV-viewing homes.

Heading into Friday night, the NBC-only coverage of the Rio Olympics has been averaging 28.7 million viewers and a 15.9 household rating.

Those numbers are still down from London four years ago, but NBC Sports continues to see record returns from streaming. Live-streamed minutes of the Rio Games have now reached 1.5 billion.
