In a video posted on July 21, 2009, YouTube software engineer Peter Bradshaw announced that YouTube users could now upload 3D videos. The videos can be viewed in several different ways, including the common anaglyph (cyan/red lens) method which utilizes glasses worn by the viewer to achieve the 3D effect. The YouTube Flash player can display stereoscopic content interleaved in rows, columns or a checkerboard pattern, side-by-side or anaglyph using a red/cyan, green/magenta or blue/yellow combination. In May 2011, an HTML5 version of the YouTube player began supporting side-by-side 3D footage that is compatible with Nvidia 3D Vision. The feature set has since been reduced, and the 3D feature currently only supports red/cyan anaglyph with no side-by-side support.
YouTube originally offered videos at only one quality level, displayed at a resolution of 320×240 pixels using the Sorenson Spark codec (a variant of H.263), with mono MP3 audio. In June 2007, YouTube added an option to watch videos in 3GP format on mobile phones. In March 2008, a high-quality mode was added, which increased the resolution to 480×360 pixels. In December 2008, 720p HD support was added. At the time of the 720p launch, the YouTube player was changed from a 4:3 aspect ratio to a widescreen 16:9. With this new feature, YouTube began a switchover to H.264/MPEG-4 AVC as its default video compression format. In November 2009, 1080p HD support was added. In July 2010, YouTube announced that it had launched a range of videos in 4K format, which allows a resolution of up to 4096×3072 pixels. In March 2015, support for 4K resolution was added, with the videos playing at 3840 × 2160 pixels. In June 2015, support for 8K resolution was added, with the videos playing at 7680×4320 pixels. In November 2016, support for HDR video was added which can be encoded with Hybrid Log-Gamma (HLG) or Perceptual Quantizer (PQ). HDR video can be encoded with the Rec. 2020 color space.

More InfoIn 2006, Google moved into about 300,000 square feet (27,900 m2) of office space in New York City, at 111 Eighth Avenue in Manhattan. The office was designed and built specially for Google, and houses its largest advertising sales team, which has been instrumental in securing large partnerships. In 2010, Google bought the building housing the headquarter, in a deal that valued the property at around $1.9 billion. In March 2018, Google's parent company Alphabet bought the nearby Chelsea Market building for $2.4 billion. The sale is touted as one of the most expensive real estate transactions for a single building in the history of New York. In November 2018, Google announced its plan to expand its New York City office to a capacity of 12,000 employees. The same December, it was announced that a $1 billion, 1,700,000-square-foot (160,000 m2) headquarters for Google would be built in Manhattan's Hudson Square neighborhood. Called Google Hudson Square, the new campus is projected to more than double the number of Google employees working in New York City.
