The following article will explain What is Roku and answer any questions you may have about this media streaming device.

Roku is regarded as one of the top brands in the streaming market and has been popular among cord-cutters since the first version was launched in 2008.

It’s functionality and features rival that of the Amazon Firestick, another popular streaming media player that ranks at the top of home entertainment streaming technologies.

Using a streaming device such as Roku or Amazon Firestick lets you access movies, news, TV shows, podcasts and music without having to download them to your hard drive. This saves you a lot of storage space in your devices.

Although we cover Roku devices on this Website, we don’t recommend them due to their closed system. We recommend the Amazon Fire TV Stick 4K due to its low price and ability to easily Jailbreak it which will allow for free movies, TV shows, live channels, ppv, sports, games, and more.

Because streaming sticks are designed to be handy, you can take your mobile entertainment system wherever you go.

There are thousands of content options you can choose from to suit your video and audio streaming preferences.

What is Roku

Roku is a brand of digital media players that was first founded in October 2002 by the founder of DVR manufacturer ReplayTV, Anthony Wood.

Named after the Japanese language term for “six” (since it was Wood’s sixth startup), the company was incorporated in early 2008 when Netflix dismissed the plan of building its own streaming player.

Wood, Netflix’s Vice President at that time, was successful at securing the media services provider’s investment to build the first Roku device.

Roku has since become extremely popular among cord-cutters when it went public in 2017 with $1.3 billion in stock market valuation.

Today, Roku is known for its streaming sticks that cater to budget-conscious cord-cutters.

However, they also offer other devices such as soundbars and smart TVs for those who want to level up their entertainment experience.

History of Roku Devices

The Roku series of streaming players have gone through eight generations already. The original streaming receiver box, Roku DVP, was developed in 2008 for Netflix streaming and was limited to show only SD content.

Three years after, THE Roku SD, Roku HD, and Roku HD-XR set top boxes were launched.

In 2011, the second generation was launched with the introduction of Roku 2 XS and the budget friendly Roku LT.

In 2013, the Roku 3 was introduced as the third generation of player that featured a better CPU compared to its predecessors with a Wi-Fi Direct remote system.

Then came the next generation with Roku 4 in 2015 that was already capable of 4K video streaming.

Less than a year after, the fifth generation was launched with Roku Express and Express+, Roku Premier and Premier+ and Roku Ultra.

These models were then further upgraded as part of the next generation in 2017 along with the Streaming Stick+.

The seventh generation introduced in mid-2018 had minor product enhancements.

In 2019, the latest generation made its way into the market with a smaller Roku Express, a new operating system (OS) version, and better compatibility.

Netflix, however, has stopped supporting older Roku devices such as the Roku SD, HD, and HD-XR. You can get to know more about this in our previous post below.
