It's Day 2 of the Apple antitrust trial in Oakland, California, and sparks could fly on the witness stand.
Apple is fighting allegations that it violated antitrust laws between 2006 and 2009. The case hinges on this question: Was an iPod update in 2006 a legitimate product improvement or an illegal anticompetitive move?
Apple says it was perfectly legitimate, as the update made movies as well as album art available on the iPod for the first time, and included important security upgrades.
Plaintiffs lawyers disagree, saying the purpose of the update was to stifle competition. After that update, music from rivals like RealNetworks would not play on Apple devices.
They say Apple's executives were trying to maintain and expand their monopoly on the portable digital media player market. By 2004, according to the plaintiffs, Apple controlled 70 percent of that market.
