I believe it depends on your definition of largest. Do you mean the developers with the most app releases? Or the ones with the most downloaded applications? In addition, there is a difference between publishers and developers. The companies included in the official CTV app shops are publishers. In certain instances, these organizations are also app developers, however publishers typically contract third-party app developers to create their apps.
Regardless, OTT devices such as Roku, Chromecast, Apple TV, and Amazon Fire TV dominate the market for linked TV streaming. Meanwhile, Netflix, Hulu, Disney+, YouTube, HBO, and Amazon Prime Video dominate the market for streaming apps.
The most downloaded apps for each platform are as follows:
Roku Channel Store: Netflix
iTunes TV TVs Application Store: Disney Winding Road
Amazon YouTube on FireTV
The following are the most prolific publishers in terms of the number of apps produced by the platform:
Roku Channel Store: Sub splash Inc — 841 apps
Apple TV TVs App Store: Cross Media Corporation — 194 apps
OTT Solutions, Media Management, and Delivery, Ad-Network - 436 Apps on Amazon Fire TV
Finding a business that specializes in mobile app and CTV intelligence is your best bet if you want to go further into the details.
For example, our File Dumps for Connected TV apps (which you can download and test for free) allow you to view metadata for all published and unpublished CTV apps, such as publisher name, publication ID, and other insights.
