Last month, Netflix made the surprising decision to kill off a key feature: With no prior warning, the company removed the ability to cast videos from its mobile apps to a wide range of smart TVs and streaming devices. Casting is now only supported on older Chromecast streaming adapters that didn’t ship with a remote, Nest Hub smart displays, and select Vizio and Compal smart TVs.
That’s a stunning departure for the company. Prior to those changes, Netflix allowed casting to a wide range of devices that officially supported Google’s casting technology, including Android TVs made by companies like Philips, Polaroid, Sharp, Skyworth, Soniq, Sony, Toshiba, and Vizio, according to an archived version of Netflix’s website.
But the streaming service didn’t stop there. Prior to last month’s changes, Netflix also offered what the company called “Netflix 2nd Screen” casting functionality on a wide range of additional devices, including Sony’s PlayStation, TVs made by LG and Samsung, Roku TVs and streaming adapters, and many other devices. Basically, if a smart TV or streaming device was running the Netflix app, it most likely also supported casting.
That’s because Netflix actually laid the groundwork for this technology 15 years ago. Back in 2011, some of the company’s engineers were exploring ways to more tightly integrate people’s phones with their TVs. “At about the same time, we learned that the YouTube team was interested in much the same thing — they had already started to do some work on [second] screen use cases,” said Scott Mirer, director of product management at Netflix at the time, in 2013.
The two companies started to collaborate and enlist help from TV makers like Sony and Samsung. The result was DIAL (short for “Discovery and Launch”) — an open second-screen protocol that formalized casting.
In 2012, Netflix was the first major streaming service to add a casting feature to its mobile app, which at the time allowed PlayStation 3 owners to launch video playback from their phones. A year later, Google launched its very first Chromecast dongle, which took ideas from DIAL and incorporated them into Google’s own proprietary casting technology.
For a while, casting was extremely popular. Google sold over 100 million Chromecast adapters, and Vizio even built a whole TV around casting, which shipped with a tablet instead of a remote. (It flopped. Turns out people still love physical remotes.)
But as smart TVs became more capable, and streaming services invested more heavily into native apps on those TVs, the need for casting gradually decreased. At CES, a streaming service operator told me that casting used to be absolutely essential for his service. Nowadays, even among the service’s Android users, only about 10 percent are casting.
