It's possible to use a single device and have plenty of television entertainment options for the entire family. On the other hand, you can expand your online TV viewing sources with more devices. How many should you use? That's up to you. I usually suggest that you start with a single device that best suits your purposes, and if you want to expand later, you always can. There's no cost savings by doing it all at once.
Which device is best? I have my favorite, but the fact is, any one of these would be a great place to start. One may be better suited than others, depending on what you want. It's all about choice, after all.
These are some of the most popular options.
Roku is the leader in online streaming. The Roku devices support a wide variety of online sources, and can suit most needs. Roku prices range from $29 for the Roku Express to $129 for the top of the line Roku Ultra, which supports UltraHDTV (4K). Roku TVs are also available. Find out more about Roku here.
Apple TV is a great choice, particularly if you are in the Apple ecosystem. If you have iPhones, iPads, and MacBooks, the best choice might be an Apple TV. Prices range from $149 to $199. Find out more about Apple TV here.
Amazon Fire TV is the online shopping giant's entry into the streaming wars, and it's already a winner. It has a large app library, and is easy to use. If you are heavy into Amazon, particularly Amazon Prime, this may be the best solution for you. Prices range from $39 for the Stick, to $89 for the set-top box. Find out more about the Fire TV here.
Google Chromecast is the search giant's entry into the streaming market. Chromecast is one of the most popular options, but it's a little different from the others. Although it connects to your TV, it's not a set-top box, and requires another device -- usually a phone or a table -- to work. The Chromecast starts at only $35, up to $69 for the UHD (4K) version.

TiVo now supports streaming content, in addition to its traditional DVR functionality. It has the smallest collection of streaming apps of those listed here, but they are the most-used streaming apps. TiVo may be the solution for you. Read more about TiVo here.
There are other streaming devices available, but we won't be discussing them here. They may be great devices, and one of them may be the one for you. Here, we are just going to focus on the top selling, most used devices.
