A trailer of Halo 3 has helped push Microsoft's Xbox Live service to become the world's largest platform for high-definition on-demand content, surpassing 24 million downloads following the launch of Xbox360 in the US on November 22, 2005.

Over 1.5 million gamers connected to Xbox Live last week, downloading exclusive content direct from the show floor, including the latest high-definition game demos and trailers, such as Halo 3, Gears of War and Fable 2; game add-on content, such as Map Packs from Call of Duty 2 and additional quests from The Elder Scrolls IV: Oblivion.

"The sheer volume of downloads during E3 week was simply staggering. To put it in perspective, all the printed material in the US Library of Congress is estimated to be about 20 terabytes, and Xbox Live delivered 30 times that amount in just 7 days", said Peter Moore, corporate vice president of the Interactive Entertainment Business in the Entertainment and Devices Division at Microsoft.

The eagerly anticipated Halo 3 high-definition trailer proved to be the most popular download of the week:
