"Streaming video" (or VOD, Video On Demand) refers to video (like a movie) which is delivered to an end-user upon request (demand) over the Internet in a continuous transmission or stream. Typically, the video is viewed in real time, but it may also be capable of being downloaded for later viewing. When a subscription fee is charged (like Netflix), this delivery mechanism is called SVOD, Subscription Video On Demand. If you make the purchases one at a time (like iTunes), it is called TVOD, Transactional Video On Demand. These methods of delivery are different from over-the-air, cable, or satellite television, or a video on disc (DVD or Blu-ray). You can learn about these alternative methods of delivery on our Television or DVDs web pages. If you are exploring "cutting the cord," see our article entitled Cord-Cutting Options Supporting Audio Description. LAST UPDATE: Jul 12.
Many new TV sets and so-called cable boxes offer Internet access with built-in access to multiple streaming services. Alternatively, you may purchase a number of devices which plug into your TV's input port (HDMI connector), and from there you switch the input to that port, answer setup questions one time to connect to your wireless internet, possibly download one or more free apps, and then access the services listed below through this new device and its own remote. While there may be a few other similar devices, here is a list of the most popular ones:
While most of the information on this page is USA-only, we do have this list of streaming services in the UK which offer audio description as of January 2020:
You can also read this Access Services Report from 2019 to read an evaluation on how the various UK services are doing.
The following airlines are known to provide audio described content via their in-flight entertainment systems: American, ANA (Japan), British Airways, Emirates, KLM, Lufthansa, United, Virgin Atlantic, Virgin Australia. Such services would only be available on flights offering individual screens on seat backs or those which support using your own device (like an iPad or computer). Note, however, that most services do not offer audio MENUS, so you will probably need sighted assistance to select a movie with AD. For more information on accessible airline in-flight entertainment systems, see this post in the Perkins Blog: How to Watch Audio Described Movies on Your Next Flight. And from Mar '20: United Airlines introduces a fully accessible seatback entertainment system. Watch a video on the new United system.
The following section lists all we know about video streaming services, with the ones actually providing some description listed first. Most, but not all, require a subscription or pay-per-view. Our table is divided into two categories:
Note 1: Any reference to pricing is subject to change and is
rounded up to the nearest dollar. Some services offer a discount
for paying for a full year.
Note 2: Amazon's Fire TV Recast DVR, used in conjunction with a Fire Stick, is NOT a streaming service. It is a DVR for over-the-air programs, but it does support AD.

||On November 1, 2019, Apple TV+,, "the first all-original video subscription service," became available via the Apple TV app for $5/month for a family plan. According to Apple, Apple TV+ is the "new home for the world's most creative storytellers featuring exclusive original shows, movies and documentaries. It [features] a brand new slate of programming from the world's most celebrated creative artists, including Oprah Winfrey, Steven Spielberg, Jennifer Aniston, Reese Witherspoon, Octavia Spencer, J.J.

|The CBS All Access App offers access to live content (in select markets) and over 10,000 previous episodes via streaming devices like Apple TV and ChromeCast, plus iOS and Android devices and some streaming services like Prime Video. There is a fee for service for most content ($6 or $10/month). In August 2019, they began to offer some audio described content. A user who has tested this on an iPhone and Apple TV has reported some difficulty with accessibility of the App, but is otherwise pleased. He recommends using Safari on iOS. Another user says that for Apple TV: "When playing a show, swipe down for a menu: info, closed captions, and audio. Go to audio, then languages. If AD is available, it’ll be there." Other devices work similarly, except on an iPhone, the Audio Description option under Accessibility Settings is the only control. In February 2020, a user reported that while Apple devices support AD, Android devices do not. In January 2020 a user who spoke CBS All Access (at 888-274-5343) was told "they're working on getting descriptions out for every show in the library," and they even want to go back and do it for older shows like "I Love Lucy"! Another user said that you can make requests for description using the Twitter handle @CBSAAHelp or direct-message them and they’ll pass your requests along. March 29th: Please note that there have been numerous complaints about the availability of AD using the app, including things like available online via a browser but not the app, and AD not available. So this is a "work in progress..."||Star Trek Picard (and Discovery), The Twilight Zone, The Good Fight, NCIS (recent seasons), Blue Bloods|

HISTORY: Hulu and advocates from the American Council of the Blind (ACB) and Bay State Council of the Blind (BSCB) reached a settlement agreement in October 2018 to increase the accessibility of Hulu's streaming service to individuals who are blind or have low vision by January 2020. Starting 1Q2019 Hulu undertook efforts to make its website and software applications accessible via screen readers and to provide audio description tracks for some streaming content. While by January 2020 the accessibility effort seemed successful, only a limited amount of new content was described, even when description tracks were available elsewhere.

Within that group of shows, a FEW have audio description.||Minimal offerings, but includes Ken Burns' Country Music Special|
|Sorry, no examples!|
Amazon began offering audio described videos in June 2017, and they call their service Prime Video, available to the over 100 million Prime subscribers. They offer more described programming than any other service and show no sign of slowing down! They offer over 1800 movies and Amazon-produced TV shows with audio description tracks, with multiple viewing devices supported including all the "Fire" products (but not Roku). Some of the programming is available free to Amazon Prime members, while the majority of it requires a payment for either online streaming or downloading.

The Watch ABC App offers access to live content and select previous episodes from iOS mobile devices and Apple TV in select markets for free. Generally (but not always), if an ABC show offers audio description, the show will be described using the app. NOTE: To activate description, you must do so via your device settings, not the app itself. For example (with iOS devices): Settings, General, Accessibility, Audio Descriptions, On. NOTE: ABC Digital was the recipient of the ADP's 2017 Achievement in Audio Description - Media for this app!

They refer to this service as Cable-Free Live TV. Our testing indicates that audio description is available, though not 100%. For instance, one user tells us that on-demand content does not have AD, while another user says it is difficult to navigate with an Apple TV. We have also been told that Roku Sticks do not support AD here. We offer this guide to accessing YouTube TV AD, and a user offers this review.||Depends on network|

After an initial limited-area rollout in the fall of 2019, the service should be available in most places now. First-year promotional pricing is $60-$80/month, depending on plan. Initial user feedback suggests it does not support AD. We requested more information from AT&T but received no response. Articles: AT&T TV Update.

In October 2019, they said that AD was a "great suggestion" that would be passed to their Editorial Team for review.

We are not quite sure how to interpret this response until we get user feedback.||tbd|
HBO and its
two streaming services
HBO Go and
do not offer any audio description. The HBO Go App is
disappearing on July 31 and users can now sign in to HBO Max. HBO Now is being renamed
HBO Max, or for Roku or Amazon devices, just HBO for now. "The idea is that most HBO subscribers should be
using HBO Max unless the platform they pay through hasn’t struck
a deal to offer it yet. In that case, they’ll use a new
app named HBO, which is a revised version of HBO Now" (per this
6/12/20 CNBC article and others).
History: See the article HBO’s ‘My Brilliant Friend’ Discriminates Against Blind People. In mid-2019, the ACB began informal negotiations with HBO regarding AD. As of May 2020, there is no progress to report. Technically speaking, HBO has offered at least two programs with AD long ago: "Educating Peter" and "Monica and David," both of which focused on people with disabilities. But since this is so rare and with no further commitment yet, we leave them listed as not offering description.
|AT&T's WarnerMedia's HBO Max debuted on May 27 at a cost of $15/month. (A 2021 offering with ads may be lower priced and is expected to include live TV).

It is also available in the Apple TV App at launch, but it is not supported by Amazon Fire or Roku devices initially. In mid-2019, the ACB began informal negotiations with HBO regarding AD. As of May 2020, there is no progress to report, and users report that there is no AD in this App, and it is not very accessible.||None|

A lot of content has been announced, and we know this includes The Office and Parks and Rec, both of which originally had audio description tracks. They will also offer films from Universal Pictures, Focus Features, DreamWorks Animation, Illumination, and other major studios, plus original series, news, sports, late-night, and reality, some of which (like Jimmy Fallon) will be presented earlier than on TV. On launch date and as of at least May 13, voice guidance does not work for Peacock at least on the Flex Player. As of July 9, several news sources reported that Peacock does not yet have any agreements with Roku, Amazon, or Google's Chromecast and Android TV. CNBC Article.

|Philo is a low-cost subscription streaming service offering 60 channels for $20 per month including DVR. Networks include HGTV, History, Discovery, and Nickelodeon; however, Philo does not pass through any audio description. They replied to our inquiry in December 2019 with this comment: "I will ... forward this as a feature request so hopefully, popular demand can get this feature ... added soon." Jul 4: A blind user reported she is working with Philo as a beta tester to make the app more accessible. Kudos! When she asked if they would add AD for HGTV, History, etc., they investigated (kudos again) but replied that engineering thought "it would be a disproportionately large task for us to add the ability to load secondary audio tracks at this point," but they would reassess later. If you would subscribe to Philo if they offered AD, write them!||None|

They expect to roll out 175 shows the first year. Initially, anyway, they have a partnership with T-Mobile, which may give T-Mobile customers an advantage. Audio Description?

If you learn that any service above has started offering described programming, please advise the webmaster!
* Several studies from late-2015 to 2018 have shown that the dominant player in the fee streaming video market is Netflix by large margin over its nearest competitors: Amazon's Prime Video, HBO Go, Walmart's Vudu, and Hulu. (These statistics do not include the free videos on regular YouTube, a very highly used service.) iTunes actually has more described movies than Netflix has described videos, though if you count individual series episodes, Netflix exceeds iTunes. Also, iTunes only offers movies, while Netflix has a constant influx of new content, and it is all included for one fee, so we still consider Netflix "dominant."
