==History==

NDI was publicly revealed by NewTek on 8 September 2015 and was demonstrated at the IBC[[International broadcastBroadcasting exhibitionConvention]] in Amsterdam that week.<ref>{{cite web|url=https://www.provideocoalition.com/newtek-announces-ndi-an-open-protocol-for-ip-production-workflow/|title=NewTek announces NDI, an open protocol for IP production workflow by Allan Tépper|date=8 September 2015|website=Provideocoalition.com}}</ref> The first device shown using NDI was the NewTek [[TriCaster]] which delivered an NDI feed from each of its SDI inputs as well as four output feeds from its vision mixer. The TriCaster could also receive up to two NDI sources from other devices (increased to 12 in later releases and up to 44 in NewTek's IP Series).<ref>{{cite web|url=http://www.sportsvideo.org/2016/09/19/newteks-will-waters-says-ip-series-will-appeal-to-new-markets/|title=NewTek's IP Series Video-Production System Targets New Markets|first1=Ken|last1=Kerschbaumer|date=September 19, 2016|website=Sports Video Group}}</ref><!--[[User:Kvng/RTH]]-->

NewTek had previously created a predecessor of NDI called AirSend to get video from external devices into their TriCaster products. AirSend had been implemented by a number of [[character generator]] (CG) vendors including [[Vizrt]] and [[ChyronHego|Chyron]]. In order to quickly bring these products into the NDI space, NewTek created a new driver to replace the existing AirSend driver, which could be installed on these existing AirSend-compatible devices, instantly converting them to NDI-compatible devices with no change required by the original CG vendors.<ref>{{cite web|url=http://pages.newtek.com/NDI-Upgrader-Download.html|title=NDI AirSend Updater-NewTek|website=pages.newtek.com}}</ref>
