My DirecTV allows instant access to YouTube straight through them, no internet needed. Its just like I'm watching a recorded program on the TV.

The apps mentioned that are on Roku, most Blu-ray players and other Smart devices typically are popular sites (Netflix, YouTube, etc.).  You won't find an app for bassresource.com or other specialty sites on these devices.

 

However, most of the better Smart TV's made by Sony, Samsung & Sharp also feature a web browser.  This way you can access just about any website on your TV without having to connect or disconnect your laptop or phone (be it wired or mirrored).  This will become a more normal feature for TV's in the coming years.

Lots of $$ invested in the Apple ecosystem, so it's all Apple TV for me and the fam. Same thing can be done from any iDevice

Apple TV makes an appearance on page 2? 

Another Chromecast user here. The new Chromecast app allows you to cast your entire screen so it doesn't even matter if you have applicable apps now - everything works. It is fantastic.

Somebody mentioned most fishing series are bad, while that may be true I love watching Addictive Fishing with Blair Wiggins. Its 99% saltwater but its good stuff. He has a channel on YouTube and I believe they have five seasons on episodes on there right now. Just watched him catch reds and trout in Vero Beach, FL.

It sure is amazing how far technology has come in the last 10yrs alone! So many options!!
