If you've heard about the 33 trapped Chilean miners (and let's face it, who hasn't) which are 2000 feet underground. After months of being trapped, the miners are being rescued one by one and media organisations have been broadcasting the footage (since yesterday) to a reported 1 billion people. The worldwide audience has led to live-streaming service Ustream to break records.
Ustream reported that it served 5.3 million stream over the course of the rescue, gathering figures in a 24 hour period over October 11 (4AM to 4AM). To think of this in other efforts or tragedies, Michael Jackson's memorial gathered 4.6 million streams while President Obama's inauguration drew 3.8 million Ustreamers. Of course, the Chilean miners stream did last longer (in time) but the numbers are nonetheless impressive.
Other sites that feed video such as CNN have seen high numbers of streams - 1.2 million live video streams on Tuesday with over 2 million Wednesday. But, that's not a record for them - with a massive 26.9 million streams for Obama's inauguration.
