Well, in any case..... you won't miss a single event of Olympics LIVE, if you are willing to get up at about 4 AM EST (or 1 AM PST) to see what will be starting around 9-10AM in London.
Just a minor correction to your otherwise excellent posts on the subject: you mean EDT (or PDT).
The biggest issue NBC has is that they have contract obligations with local stations that get half an hour of local news between 6 and 6:30, followed by national news, and half an hour of local news between 11:00 and 11:30, and they have to do this in 4 different time zones, so basically every hour for 4 hours straight one part of the country is "offline" to the national NBC feed, so to speak, so it is hard to fit in the live feeds at the same time.
And an even more minor correction: in the Central time zone, the time set aside for local news is at 5:00 and 10:00 (with national news at 5:30), which means they can share a feed with the Eastern time zone -- so there are really only 3 different "time zones" that NBC deals with. Although what NBC has done in the past is give the local affiliates at least 90 minutes in the evening, starting prime-time Olympics coverage at 7:30 Eastern/6:30 Central, thus allowing Eastern affiliates to show a half-hour of their regular syndicated programming at 7:00, and allowing Central affiliates to have either local news or syndicated programming at 6:00.
