What is NAB Show Express?

In a rapid response to COVID-19, NAB Show in April was canceled and preparations began for an online experience. The new digital event was labeled NAB Show Express and allowed exhibitors to share product information, announcements and demos, as well as deliver educational content via a broadcast stream and video-on-demand. NAB Show Express also created innovative opportunities for the community to interact virtually, so the content community could come together in a new way. NAB Show, held annually in Las Vegas, is the world's largest convention attracting those in media, entertainment and technology. With more than 90,000 attendees from 150+ countries and 1,500+ exhibitors in 2019, NAB Show is the ultimate marketplace for solutions that transcend traditional broadcasting and fuel the digital storytelling economy. From creation to consumption, across multiple platforms, NAB Show is where global visionaries convene to bring content to life in new and exciting ways. It was going to be a huge challenge to shift the traditional format online whilst giving the NAB Show’s exhibitors, audience and partners the quality experience and networking opportunities they were used to.

"CaptionHub was selected for its ability to deliver subtitles at the scale needed by NAB"

Why CaptionHub?

"NAB contacted CaptionHub just two weeks before NAB Express went live. It was a big ask: shifting all the content online at a magnitude which hasn’t been done before in any industry. NAB needed to ensure that all the content was accessible to its deaf or hard of hearing audience members, and approached CaptionHub because of our cutting-edge automatic speech recognition technology which creates accurate captions, our in-built translation tools, our ability to deliver at speed and the fact that we can handle large volumes of video content.

Leveraging its existing integration with online video platform partner Brightcove, CaptionHub provided a simple, effective route for NAB to ingest and publish subtitles."

A successful result and blueprint for online events

The National Association of Broadcasters (NAB) saw an estimated 40,000 industry professionals at the inaugural NAB Show Express. Participants from around the world engaged with content through social media streams, partner programs and directly via In total, participants consumed more than 1.6 million minutes of video content via the event’s broadcast channels, on-demand videos and social media streams in the first week of the event. For the first time, using CaptionHub’s integrated machine transcription, key sessions were captioned, so NAB’s reach for the hard of hearing was made possible, underscoring NAB’s commitment to improve accessibility for all. For an event of this magnitude, this was a broadcast industry first, and its success paves the way for future mass online events which will be seen to massively enhance the conference world.
