Xbox Live
When the Xbox launched on November 15, 2001, the as-yet unnamed online service was destined for a Summer 2002 deployment. Xbox Live was finally given a name at E3 2002 when the service was unveiled in its entirety. Sound-dampened booths and broadband-connected Xbox consoles—featuring an early version of "Unreal Championship"—demonstrated the service on the show floor. The Epic title was one of the flagship titles for the service, which was slated for a debut on November 15, 2002, marking the anniversary of the Xbox launch. Microsoft announced that 50 Xbox Live titles would be available by the end of 2003. Utilizing the required broadband bandwidth, Xbox Live featured a unified gaming "Friends List", as well as a single identity across all titles (regardless of the publisher), and standardized voice chat with a headset and communication, a feature that was still in its infancy.
Xbox One
Later on, critics felt that the Xbox One's functionality had matured over the year following its launch; Jeff Bakalar of "CNET", assigning it a score of 8/10, acknowledged improvements to Xbox One's software since its original release, but that its user interface was still unintuitive in comparison to Xbox 360 and PlayStation 4, explaining that "navigating the interface seems to be much more problematic than it rightfully should be, and there's simply not enough transparency in the logic within it. There are oddities peppered throughout, which is the root for countless headaches and frustrations." Xbox One's in-game performance was mixed, with some titles showing slower performance over PS4, but some multi-platform games performing better on Xbox One than PS4. CNET praised the wider lineup of multimedia services and apps on Xbox One over PS4, not requiring Xbox Live Gold for online save data storage, support for high-speed USB 3.0 as secondary storage, and having a "slightly better" lineup of upcoming exclusives, concluding that "While the PS4 had a clear advantage at launch, that edge is slowly evaporating as Microsoft has worked feverishly to undo most of the Xbox One's original missteps."
