consoles and personal computers, making the porting of games between these systems much easier. Later hardware improvements pushed for higher frame rates at up to 4K resolutions. Digital distribution increased in popularity, while the addition and improvements to remote play capabilities became standard, and second screen experiences via companion apps added more interactivity to games. The Wii U, introduced in 2012, was considered by Nintendo to be a successor to the Wii but geared to more serious players. The console supported backward compatibility with the Wii, including its motion controls, and introduced the Wii U GamePad, a tablet/controller hybrid that acted as a second screen. Nintendo further refined its network offerings to develop the Nintendo Network service to combine storefront and online connectivity services. The Wii U did not sell as well as Nintendo had planned, as they found people mistook the GamePad to be a tablet they could take with them away from the console, and the console struggled to draw the third-party developers as the Wii had. Both the PlayStation 4 and Xbox One came out in 2013. Both were similar improvements over the previous generation's respective consoles, providing more computational power to support up to 60 frames per second at 1080p resolutions for some games. Each unit also saw a similar set of revisions and repackaging to develop high- and low-end cost versions. In the case of the Xbox One, the console's initial launch had included the Kinect device but this became highly controversial in terms of potential privacy violations and lack of developer support, and by its mid-generation refresh, the Kinect had been dropped and discontinued as a game device. Both consoles eventually released upgraded hardware during their mid-cycle refresh, with Sony releasing the PlayStation 4 Pro and Microsoft releasing the Xbox One X, which allowed for higher frame rates and up to 4K resolution, in addition to Slim models, marking a departure from previous generations, while adding considerable longevity to this generation cycle. Later in the eighth generation, Nintendo released the Nintendo Switch in 2017. The Switch is considered the first hybrid game console. It uses a special CPU/GPU combination that can run at different clock frequencies depending on how it is used. It can be placed into a special docking unit that is hooked to a television and a permanent power supply, allowing faster clock frequencies to be used to be played at higher
