The first Zune model, the Zune 30, was released in the United States on November 14, 2006, featuring a capacity of 30 gigabytes, FM radio, and a 3 inch screen. The Zune 30 was initially available in black, brown or white. Retail packages contained a pair of basic headphones, a carrying case, USB cord, and a software CD.
The Zune 80 was announced on October 2, 2007, along with the smaller Zune 4 and Zune 8 to compete with Apple's iPod nano line. These were to be known as the second generation of Zune devices. The Zune 80 featured a 3.2 inch screen, while the Zune 4 and 8 come with an 1.8 inch screen. Both come with a new touchpad-style input device ("squircle", as fans called it) and new software. Additional file support for H.264 and MPEG-4 formats was also included, whereas the older Zune 30 requires these formats to be transcoded to WMV prior to sync. The ability to sync wirelessly (automatically if connected to a power supply), podcast support, and an upgraded song-sharing licensing are now available on all models. The new software also allows a Zune device to communicate with other Zune devices to share pictures and songs. A free firmware update added the new software features to the original Zune 30, and was released on November 13, 2007. The Zune 80 came bundled with a USB connection cord and premium headphones. The Zune 4 and 8 come with a USB connection cord and basic headphones.
The third-generation Zune 16 and Zune 120 devices were released in September 2008, coinciding with the release of the Zune Software 3.0 update.
On May 26, 2009 Microsoft announced the Zune HD, the first touch screen Zune. The Zune HD has HD Radio and the ability to display video in High Definition through a docking station (sold separately). The screen is multi-touch enabled and uses gestures such as swiping and pinching throughout the player.
