The number of US homes without a TV doubled in just 6 years

A survey by the US Energy Information Administration reveals some startling details about television use in American homes.

The amount of homes that don't own a TV has doubled since 2009. According to the USEI survey, 2.6% of American homes didn't have a TV in 2015. That's a huge increase from the 1.3% of American homes that didn't have a television in 2009.

In fact, from 1997 to 2009, the percentage remained stable at 1.3%, except for 2001, when the percentage was 1.2%.

The huge surge in homes without TVs proves that companies making TV content can't ignore that viewers are turning to other screens, such as computers and mobile devices, to access their video.

The survey also shows that homes that do own TVs are using fewer of them. There is an average of 2.3 TVs in an American home, down from 2.6 per household in 2009.

It isn't a surprise that the group that uses the least amount of TVs in their homes is people younger than 25 years old. The group that uses the most amount of TVs at home are those older than 75.

Next to peripheral TV equipment - such as cable boxes, digital video recorders (DVRs), and video-game consoles - smartphones are the most-used non-TV gadget and most popular among those aged 34 years old and younger - basically, millennials.

TV networks have been fearing this shift away from traditional viewing for years and have been slow to act on it. Streaming offerings like Netflix and Hulu are providing fans with their favorite shows and availability across multiple devices.

Amazon Prime Video and Netflix then took that a step further by making content available for download to watch offline.

There's also a growing battle among DirecTV Now, Sling TV, PlayStation Vue, and now YouTube to offer all the diversity of a cable subscription with a streaming product.
