A new Web based service, located at http://guidebox.com will help you to search and catch up TV shows you have missed. Another reason for you to perhaps cut your expensive cable subscription.
At anytime, go to the site, even on your mobile devices, select the national broadcasting channels including ABC, NBC, CBS, Fox, Comedy Central, HGTV, etc… and episode of their full length TV shows and start watching via your Web browser. If you are in the Apple ecosystem with an iPad and an Apple TV tethered to your living room TV then you can send Airplay stream wirelessly to your TV.. No DVR needed.
Guidebox suggests free streaming services but if what you are looking for is not available, the service will direct you to paid services such Hulu Plus, Netflix, iTunes, Amazon, etc.. should you insist.
The service conveniently lets you add shows to your favorite to get update when new show becomes available in your watch later queue..
