We at last100 love our set-top boxes. Or at least we love the idea of getting digital video content off the Web and onto our televisions in the living room. But here’s a device we didn’t anticipate.

FyreTV has developed a nondescript set-top box dedicated solely to porn. Nothing else. For $10 a month, you can stream as much adult content as you can possibly watch. Eliot Van Buskirk of Wired’s gadget lab did some snooping this week and found FyreTV, not at the Consumer Electronics Show but at the Adult Entertainment Expo, which runs parallel to CES.

Buskirk notes that the design of the FyreTV is innocuous looking, simply a little black box — like a plain brown wrapper — that can stream more than 20,000 titles from leading adult studios right into your living room or, dare we say, the boudoir.

FyreTV sits next to the TV, is connected by wired Ethernet, and costs nothing but the $10 monthly fee. It has no hard drive. It streams movies at full DVD quality, offers 4:3 and 16:9 aspect ratios, and includes HDMI, S-Video, component, and composite outputs.

In a way, it’s odd that the adult industry is just getting around to offering a dedicated set-top box for its content. Historically, porn has led the charge (believe it or not) for the early-adopter acceptance of many consumer electronic devices and services — from the VHS (over Betamax) to DVDs to secure payment methods for goods and services over the Internet.

Wonder which side porn has taken in the Blu-Ray vs. HD-DVD format war?
