Looks like Samsung has expanded its Explore 3D app with free, on-demand content and a US launch. Great news if you have the proper TV. It includes music videos, movie trailers, educational content and even full-length TV shows from Wealth TV, among others. At a later date, studios will offer paid content through the app, which is available on samsung’s connected 3D LED-lit LCDs and 3D plasma TVs.

The paid content will arrive later this year and include feature films, shorts and full-length documentaries. The service will require signing up for an account using a PC.

Philips Blu-ray players will now be shipping with BLOCKBUSTER On Demand, offering another way for Blockbuster to offer consumers instant access to the latest movies. It will work with the Philips 5320 and 7320 Blu-ray models.

They are a little late to the party on this one and we don’t see them knocking Netflix down anytime soon. Most of us already have a PS3, after all. But if this catches your movie viewing fancy, the On Demand service offers comprehensive on-screen search and browsing capabilities, as well as full details, ratings, trailers and additional information concerning each movie.

Despite the name, the folks at Slacker are anything but. They’ve just announced that their Internet radio service will blossom into a full on-demand system, as subscribers can now have access to a new paid feature that will include the option of finding and playing specific songs, as well as creating their own playlists.

Unlike other services like Rhapsody, the radio feature can come into play even in this mode and will auto-create a playlist based on favorited songs and create a larger radio station out of a user-made playlist. You gain controls such as skipping back through songs.

Here’s something that makes perfect sense and we’re surprised that it has taken so long. With Amazon’s Disc+ on Demand, when you buy a DVD or Blu-ray movie, you will be able to stream it instantly via Amazon On Demand. Pretty awesome huh?

Looks like it applies to a few hundred titles so far and for the moment it’s just for those in the US, but it should have no problem being successful and should grow quickly. You’ll need to look for the Disc+ on Demand logo on movie pages to make sure it’s eligible.

Here’s some more Microsoft news, in a day filled with Microsoft news. How does full Xbox Live games on demand sound? Awesome? I know. You, and me, can now download Mass Effect, Bioshock and others. And you can do so like a big boy, using a real credit card, not Xbox Live points. They will be coming in August.

It would be great if you could get every game, but sadly you can’t. It’s a mix of third-party stuff like Sonic, call of Duty 2, Crackdown, Bioshock Mass Effect and others. Whether games will be downloadable the day they’re released to retail is unclear. Also don’t expect to use your credit card direct just yet: “We’re not getting rid of the point system.”

PlayStation has partnered with Sky to create a new video-on-demand download service called Go!View. As in…Go and view. Very clever. Those guys who name stuff really earned their money on that one. It will allow users to create TV schedules for their PSPs, completely tailored to suit the users individual needs and tastes.

You’ll be able to choose from a wide range of stuff like comedy, entertainment, sports and movies. You download it from your PC and watch wherever and whenever you damn well like. Never miss anything ever again. It works on a subscription or pay-per-view basis.
