Are you sure ?

It seems restricted to Top 20 were Blu Ray and DVD have concurrent sales.

Also it deals with revenue. This in fairness is common practice (dollars are a good common denominator after all). However the way the chart is represented it could be viewed by some as a strict unit to unit battle.

Given the price discrepancy at POS the sales on concurrent DVD vs Bluray in units sold ratio form would be closer to 95:5

Once you take into account the thousands of titles that are DVD only you get a better picture of the battle facing BR.

Absolutely positive, Home Media Research switched last year to Total Revenue to better indicate the progress of Blu-ray.  Basically to show its true position for the week.   So dont confuse the addition of the other charts.  They are there just to show how the Top 20 of each category are doing.  Think of it like Box Office charts,  even though they only show top ten Box Office hits for the week, when they show total revenue its for every movie that was in theatres.  

Also if I am calculating correctly,  if it was only Top 20   Blu-ray ratio would be closer to 16:84.  

well the way things are going it wont be too much longer until blu-ray completly takes ov dvd

know that HD DVD is dead (YAAAAAAAAAAAAAAAY)

Do not think I will buy a Blue-Ray for a long long time. To be Honest for me their is no point. I hardy watch movies unless I go to a friends house. Only reason I ever got a DVD player was because a old live in girlfriend wanted one.

I dont know what the point of this comment is,  this is a Blu-ray sales tracking thread, not a "What do you think of Blu-ray" thread

Actually the way things are going it is going to take some serious intervention from the BDA for Blu-ray to take over DVD anytime soon

I agree with the above which to echo my early points could mean

Timed exclusivity for Blu Ray releases and or deletion of content on standard DVD's

Pro - People who want to see the movie early will be forced into buying Blu

Cons - Piracy will probably step up to the plate, Potential lost revenues due to customer backlash

I still believe the real trick will be to bring prices down on the media. Until Blu Ray is at the same price point as a DVD it will also be second fiddle.

Also bit more of an effort to get obscure titles on Blu Ray. The major Hollywood studios and Blockbusters are fine but some people love Period drama, others love old TV series. These niche products are only available on DVD. That needs to change.

You miss a crucial point:

The BDA has no real power!

Outside of the technical standard they are mainly a marketing instrument, but 6they don't really have much money or influence.

They can't order their members to do something, and that is the problem.

The individual companies thzemself control their titles and prices. In fact if one company would decide to got purely to Blu-ray competitors will try to offer alternatives on DVD to increase their own market share.

Most casual buyers are very price sensitive. They don't necessarily buy a title when it arrives, but when its price appeals to them. This makes a timed release extremly difficult. They might come to a store due to marketting of one film, but if they have doubts if it is worth the price, they only need to see another title that they thought about and if its DVD is cheap they lerave the store with the DVD and decide to wait till the original movie is cheaper (and on DVD)...

A few of your points are quite wrong. 

The BDA has more power than you give credit for.  They include every major movie production company in the world, if one starts doing something that will help with Blu-ray adoption,  the others will follow. 

The individual companies do not control the retail prices,  only the MSRP,  and only a moron would buy a movie at MSRP.   DVDs wouldnt even sell if they sold for their MSRP.   No its the retailers that decide what price you pay and how much or little profit they make to get you through their doors.  Which is their number 1 priority.

@bolded
A large percentage of movie sales come in the first 2 weeks for each movie,  which also just happens to be the time when most retailers put them on sale.  After a few weeks the retailers raise the price back up to "regular price", and sales drop to normal weekly rates.  This is exactly why BD exclusive titles will work,  Blu-ray movies show up a month before the DVD counterpart, for around $20-22 like most new releases seem to start at,  and people will adopt at a much faster rate. 

I believe this happened once before........, oh thats right it did,  DVD did the same to VHS.
