Amazon Launches 4K Streaming Video for Prime Members - WSJ

I'm guessing "actual results may vary" with Comcast and Verizon Internet services...

"Prices are falling on 4K—or “Ultra HD”—TVs that have four times the pixels of today’s high-definition models. The trouble has been finding the right content to go with them. Netflix was first with streaming 4K video, and Amazon on Tuesday made good on its pledge in November to introduce its own 4K catalog.

For now, Amazon’s 4K programming is available to members of the retailer’s Prime club. It includes original Amazon series such as “Alpha House” and “Transparent,” along with the BBC series “Orphan Black” and select (though not especially fresh) Sony movies such as “Crouching Tiger, Hidden Dragon” and “Philadelphia.” Amazon plans to add to its 4K Prime content beginning later this year."
