What references do you want to make the graphs believeable?

If you go by revenue it may give a slight skew in favor of the more expensive Blu Ray. But if you go by units sold then it gives a huge advantage to the DVD which has a much smaller margin. a chart based on profit would be impossible but I bet people would still call foul because the BD has a higher price tag and a higher margin because it is a newer technology.

This chart is the most reasonable indicator as it shows how much people are willing to spend on either technology. Just because someone chooses to spend their $20 on one BD movie doesn't mean they have less consumer spending power than someone that decides to spend their $20 on two DVDs.

Is should clearly reference that the source is revenue stream, and which source is providing said data.

Unless the graph is being presented in a cut down form, then they havent done this !

Because you say so?  Or because you refuse to go to the website where the graph comes from and learn about it?

No all charts or graphical representations of data should be clearly labelled and reference source. Otherwise they would be worthless.

It is an industry trusted source.  Here is their website if you want to learn about them.

I already visited it some time ago. In fairness it does provide some info, but worryingly it states its own research dept is its source.

Whats that expression "Who polices the police ?"

Internal Affairs does.

Yeah I think that saying is a bit outdated. You might want to find a new one...
