Steve Ferguson woke up early on Friday -- 3 a.m. to be exact -- to watch his stepdaughter Margaux Isaksen, a 16-year-old Olympian, complete a grueling 11-hour performance in the modern pentathlon.
Mr. Ferguson did not watch Margaux compete in person. From his home in Fayetteville, Ark., he watched a live stream of her sport on NBCOlympics.com, where 2,200 live hours of the Summer Olympics were shown for Internet users.
The ratings for NBC's television coverage of the Games were record-breaking this month. But the extent to which the Internet served as a supplement to television was unprecedented, and there were two clear winners: NBC's own Web site and Yahoo's Olympics section.
