Crowds viewing the 9/11 multicasts at Networld+Interop
![Page 46: John Krienke jcwk@umich.edu 1. Spell Check? Separated at birth? John Krenicki, GE E John Krienke, Gee … 2.](https://reader035.fdocuments.in/reader035/viewer/2022062309/56649e695503460f94b654d2/html5/thumbnails/46.jpg)
Eyewitness AccountsWe had a large plasma screen in the iLabs [at Networld+Interop] intended to demonstrate high rate HDTV over I2. We came in Tuesday morning and were preparing for the first day of the show when word came in about the initial plane crash into the towers. Our I2 Lead, Roy Hockett was able to switch the stream to a CNN broadcast from UMich. We began attracting exhibitors to the display even before the showfloor opened. Once the attendees were on the floor, the crowd had grown to well over a hundred.
By this point, three things had happened. The crowds around the one display had grown so large as to constitute a fire hazard, all the major news web sites had completely melted down, and CNN was being multicast from several sources. We then started loading multicast tools on every PC in the NOC, from the one driving the large video wall to people's individual laptops. By 10:30 (about half an hour after the floor opened) we had at least 3 large displays as well as a number of normal monitors turned out towards the plexiglass walls.
Soon after, we had a good number of exhibitors come and ask how to get "the CNN viewer software.”

“What information consumes is rather obvious: it consumes the attention of its recipients. Hence a wealth of information creates a poverty of attention, and a need to allocate that attention efficiently among the overabundance of information sources that might consume it.”
–Herbert Alexander Simon, economist, Nobel laureate (1916-2001)

A platform for Content Alteration Hulu to Alternate proportions
What can I, the public, add? Using SMIL or mashups, can I add: Audio tracks, captions, language dub translations, thought bubbles, video inserts, green screen in my own local backdrops (The Bionic Woman is in my room!), paint mustaches, make it funnier, sadder, stranger, share and get ratings for my version of the show (reputation systems, build my personal brand).
It’s all about adding my image: Elfyourself.com, photo-insert eCards What can I subtract?
Editing based on Parental guidance, Religious affiliation What can I change?
Can I change the ending or re-arrange the story to make it even better? Can I click on embedded products and get more info? I love that shirt! I
want those shoes! Is her hair colored? Can I click on that pizza and get the nearest pizza shop to deliver one? I love this background music – I want it!
Can I click on characters I don’t like or scenes that are too slow and vote them out? Or confusing parts I need repeated?
