Me neither, if they're not CG or sci fi it's more practical to just stream them or wait for them to come in the mail.

SONY who is the biggest producer of Blu ray probably doesn't care because its been widely accepted by the gaming industry as an prefered disk over DVD due to extra space. 

Because it has no exclusives...If they want Blu Ray becomes main stream the only thing they have do is make some big moviehits only on blu ray..

Sorry but the new Harry potter movie, new Twilight movie, new Justin Biebier on tour movie is only on blu ray..And sales will jump! ...

Yes.  Widely prefered... by a whole 1/3rd of the consoles out there.

Wii 2 and 720 won't be using Blu-rays either, you could be pretty sure on that.

Also, yeah... the Videogame Industry totally = The movie Industry (and PC industry).

Advantages of DVD over VHS

Better video and sound quality

Discs/cases take up less space than VHS

Ability to skip chapter, bookmark chapters, and navigate through menus, allowing extras such as deleted scenes, many languages worth of subtitles (or sometimes audio dubbing) on the one disc

More long lasting, and can be burnt as a backup if it is getting damaged.

Work in a variety of devices, from games consoles to computers

It's pretty damn obvious why Blu Ray failed

The issue isn't that people don't understand that Blu Ray players can play DVDs. The issue is that people understand that DVD players can't play Blu Ray! This is the reason why movie studios have started to offer double packs of DVD/Blu Ray because people want to be able to play their new movies on their legacy players.

Failed is a bit strong.  Though I agree.

Blu-ray has been more like a popular Laser Disc.

Laser Disc wasn't a complete failure.  Long after it failed to beat VHS, people still collected Laserdisc and they still put out movies for it.

It was the visual spectacle media of it's time.

After watching dark knight, toy story, inception, and social network on blu ray i could probably never go back to dvd. I guess luck me considering that blu rays are only like 2 dollars more expensive than dvds on amazon. IN some cases blu ray is cheaper

You're right, failed is too strong a term, it was going to be "failed to achieve market dominance in a similar fashion to dvd" but I got lazy.

When DVD came out, all people needed to buy was a DVD player or a PS2 to enjoy its benefits.  And even today, most people aren't utilizing it to its fullest effect, still using CRT tvs or low quality LCDs/Plasma screens which don't show much difference in quality.

Look at Blu-Ray on the other hand.  The players are still twice the price of a DVD player.  And not only that, they practically shove in your face the fact that you will never enjoy the benefits of Blu Ray without a 42" 1080p HDTV with HDMI components and 7.1 Sorround Sound Speakers.  Asking people to buy a whole new medium is always tough.  Asking them to virtually buy an entire living room set to enjoy it, is a laughing stock.

The true reason Blu Ray isn't overtaking DVD is because people aren't ready yet.  In another 5 years or so, when everyone is done replacing their TVs with an HDTV, it probably would have been fine.  But they brought it out some 8-9 years after DVDs even took hold.  Many people still are just getting into DVDs.

All that said, Blu-Ray is doing a LOT better than it did a few years ago.  It'll probably be an uphill climb, but Blu-Ray will take hold.  But like I said, not until they see a significant difference (which requires an HDTV and more).

The image on Blu-Ray is 10x better than DVD.  You just need a good HDTV to tell.  The problem was, like everything else Sony has done in the last 10 years, they focused on trying to appeal to the hardcore graphical lovers and not the vast majority of the market.
