BirdDog was an early adopter and in 2018 released Studio NDI, an [[ASIC]] implementation of NDI. BirdDog went on to deliver NDI [[PTZ camera]]s, along with a host of software applications.{{cn|date=February 2023}}
Another early adopter of NDI was [[VMix]], a Windows-based vision mixer that offers NDI inputs and outputs.<ref>{{cite web|url=https://www.thebroadcastbridge.com/content/entry/5589/studiocoast-vmix-adopts-newtek-ndi-standard|title=StudioCoast vMix Adopts NewTek NDI Standard - The Broadcast Bridge - Connecting IT to Broadcast|first=The Broadcast|last=Bridge|website=Thebroadcastbridge.com| date=18 April 2016 }}</ref> A significant increase in the NDI [[installed base]] came when live-streaming application [[XSplit]] added support for NDI.<ref>{{cite web|url=http://www.marketwired.com/press-release/xsplit-broadcaster-adopts-newtek-ndi-for-ip-production-workflow-2114230.htm |title=XSplit Broadcaster Adopts NewTek NDI for IP Production Workflow |website=Marketwired.com |date=2016-04-12 |accessdate=2017-05-23}}</ref>
Later in 2016, NewTek delivered NDI 2.0, which added features including support for service discovery across subnets. In April, Magewell announced integration of their [[PCIe]] and [[USB]] capture devices, allowing access to any video source on the network.{{fact|date=July 2023}}

In April 2019, ahead of NAB, NewTek announced the addition of Multi-TCP mode to NDI 4.0 which uses hardware [[TCP offload engine]] present in silicon, assisting lower-spec processors with NDI transport.<ref name="nab2019plans">{{Cite web | url=https://www.tvtechnology.com/news/newteks-andrew-cross-talks-about-the-acquisition-discusses-nab-show-plans |title = NewTek's Andrew Cross Discusses Acquisition, NAB Show Plans|first=Phil|last=Kurz|date=April 3, 2019}}</ref> NDI 4.0 shipped in September 2019 to coincide with the IBC exhibition.
In July 2021, NDI 5 was released adding reliable UDP transmission, redundant discovery server support, and NDI 5 Tools (NDI Bridge, NDI Remote, NDI Audio Direct, FCP-X output)<ref>{{Cite web | url=https://www.ndi.tv/tools/ | title=NDI Tools | NDI.tv }}</ref

NDI 4.x and earlier had limited support for [[ARM architecture family|ARM]], generally offering encode-only support. The release of NDI 5 brings full support for encode and decode on ARM-based processors that include [[Neon (instruction set)|Neon instructions]]. This includes [[Apple silicon]] processors.
NDI|HX devices are typically transmit-only and based on proprietary platforms with hardware H.264 encoder chips. Examples of NDI|HX devices are [[Pan–tilt–zoom camera|PTZ cameras]], and the NDI Connect Spark SDI to NDI|HX converter box. The NDI stream itself is formed at the stream consumption end via the platform-specific NDI|HX driver, presenting the same uncompressed data to the [[application software]] consuming the NDI source regardless of original HX source hardware and compression. NDI|HX2 is a purer implementation, supporting either H.264 or HEVC compression, and allows for additional NDI features.
With NDI 4.0 NewTek announced the addition of a ''Multi-TCP'' transport mode. This takes advantage of the hardware [[TCP acceleration]] in silicon which helps lower-spec processors handle heavy network load, in contrast to UDP which does not benefit from the [[hardware acceleration]].<ref>{{Cite web | url=https://www.tvtechnology.com/news/newteks-andrew-cross-talks-about-the-acquisition-discusses-nab-show-plans |title = NewTek's Andrew Cross Discusses Acquisition, NAB Show Plans| date=3 April 2019 }}</ref>
