Measuring connected TV in the U.S.

What is "connected TV"?
"Connected TV" adds programs streamed from the Internet (OTT, such as Netflix, Hulu, HBO Now, Watch ESPN, CBS News, PBS... cf. "OTT everywhere, a paradigm shift") to traditional programs (broadcast or MVPD). It does not replace traditional TV; it does not exclude it.
It is a multi-screen world and the TV set is now only one of the many screens on which we can watch programs and video (in addition to tablets, computers and smartphones).

"Connected TV" refers to a TV set that receives programs through an Internet connection (broadband, ethernet or Wi-Fi); the TV set uses a streaming device plugged into an HDMI port to access a platform. Chromecast (Google Cast technology for smartphones), Apple TV (TVos technology), Fire TV (Amazon) or Roku (Hearst, News Corp.) are the digital media streamers most frequently used. Game consoles (Nintendo, PS4, XBox One) and so-called "smart TV" sets also provide connected TV (Samsung, LG, Sony, Philips, Sharp). It is worth noting that Google, Apple and Amazon's marketshare stands at 71% (Q3 2015, Strategy Analytics).
Connected TV and traditional TV present a different user interface. Connected TV offers richer ergonomics with apps for choosing programs (browsing, searching with voice control (Siri), touch surface to swipe for Apple TV... Connected TV allows viewers to use their smartphone or tablet as a remote control. It also lets developers create new TV apps (cf. tvOS SDK, Google Cast SDK). All in all, connected TV offers a better user experience (UX).

All in all, 65% of American households have at least one kind of connected TV, according to LRG (Leichtman Research Group, April 2016). 74% of online consumers have connected TV (Frank N. Magid, May 2016, cf. supra).

By the end of April 2016, the Nielsen National TV panel will provide connected TV audience data on a daily basis for each "brand" of device. With its 100,000 panelists, Nielsen will measure 50,000 connected devices.
How important or relevant are these new analytics?
They will allow us to better observe the evolution of TV consuming behaviors, to evaluate at which speed traditional TV merges with the Net. This new consumer data will help analyze and predict the evolution of cord-cutting, subscriptions to OTT, to Netflix...
They will help us to understand the influence of the life stage, of ergonomics, on TV consumption.

According to the Nielsen Total Audience Report, 18% of US households (21.4 million) already use a connected TV set (2015), 40% of Millennials.
