VP9 is an open and royalty free video coding format being developed by Google. VP9 had earlier development names of Next Gen Open Video (NGOV) and VP-Next. VP9 is a successor to VP8. Chromium, Chrome, Firefox, and Opera support playing VP9 video format in the HTML5 video tag.

|Thanks||March 18: Mozilla added VP9 support to Firefox in version 28.|
|Thanks||September 12: Google announced that development on VP10 had begun and that after the release of VP10 they plan to have an 18-month gap between releases of video formats.|
|Thanks 2015||January 5: Nvidia officially announced the Tegra X1 SoC with full fixed-function VP9 hardware decoding.|
|Thanks||March 2: VeriSilicon announced the Hantro G2v2 decoder IP which supports VP9 Profile 2.|
|Thanks||April 3: Google released libvpx 1.4.0 which adds support for 10-bit and 12-bit bit depth, 4:2:2 and 4:4:4 chroma subsampling, and VP9 multithreaded decoding/encoding.|
|Thanks||August: Google began to publish code for VP10.|
Development of VP9 started in Q3 2011. One of the goals for VP9 is to reduce the bit rate by 50% compared to VP8 while having the same video quality. Another goal for VP9 is to improve it to the point where it would have better compression efficiency than High Efficiency Video Coding (HEVC).
On August 20, 2013, Google released Chrome 29 with VP9 final support.
On January 7, 2014, Ittiam demonstrated its VP9 decoder on ARM Cortex devices. The Ittiam VP9 Decoder, built in collaboration with ARM and Google, focuses on power, scale and portability with equal importance given to each. It runs at 1080p 30fps using the ARM Mali-T604 GPU on an Arndale board powered by Samsung’s Exynos 5 Dual SoC.
On March 2, 2015, VeriSilicon announced the Hantro G2v2 decoder IP which supports VP9 Profile 2.
The VP9 format defines four profiles: profile 0, profile 1, profile 2, and profile 3. Profile 0 allows for a bit depth of 8-bits per sample and supports 4:2:0 chroma subsampling. Profile 1, which is optional for hardware, adds support for 4:2:2 chroma subsampling, 4:4:4 chroma subsampling, alpha channel support, and depth channel support. Google later developed two high bit depth profiles: profile 2 and profile 3. Profile 2 allows for a bit depth of 10-bits to 12-bits per sample and supports 4:2:0 chroma subsampling. Profile 3 adds support for 4:2:2 chroma subsampling, 4:4:4 chroma subsampling, and alpha channel support.
- YouTube offers several resolutions of VP9 video, with Opus audio in the WebM file format, through DASH streaming, including 720p and 1080p, and is now also using VP9 for 4K resolution content.
- Some smart TVs support VP9 (see list of 4K TVs).
- In Septemer 2015, Micrsoft has announced the Edge browser in Windows 10 will add support for WebM (Opus, Vorbis, VP9)
On September 12, 2014, Google announced that development on VP10 had begun and that after the release of VP10 they plan to have an 18-month gap between releases of video formats. In August 2015, Google began to publish code for VP10.
