I live 15 time zones away (nine if you want to count it differently) from the Beijing Olympics. The last week has turned me and my friends into night owls in order to keep abreast of the best developments (for Canada, anyway) at the Games. So many of the events take place in the early-morning hours and CBC shows everything live across all time zones on the network.
NBC has shelled out enough rights money to ensure the big finals coincide with American prime-time viewing in the populous eastern time zone, but it should be noted that the rest of the country sees its work on a time shift. (Which means I can only watch the broadcast from three hours ago on NBC.) At the very least, many events are shown hours later.
That doesn't feel good if you're a computer user attached to Twitter. For days now CNN and others have been relaying results across Twitterand news alert systems to the dismay of users who don't want to spoil their viewing pleasure. Techcrunch has a story on it.
