According to company spokesman David Dennis, at least two million users have logged into Facebook, making it the most adopted of Xbox Live's new functions. Dennis said that half a million Last.fm accounts were created in the first 24 hours, and Xbox Live users streamed 120 million minutes of music.
Meanwhile, the Zune marketplace -- formerly called Xbox Live marketplace -- served videos to 1.7 million users in the first week available. No figures for Twitter's usage were offered, but Dennis did say that there have been "tweets from nearly every market where we have Xbox Live."
