.... Yesterday I was shopping at Fry's. I saw 14 or so people buying 2 or more DVD's, only 1 person (who looked rich, upper class) bought Blu-Ray, and it was only 1 disc, and it was discounted. So no, Blu-Ray is not gaining market share. ....
Wow - I'm convinced by your argument. So based on:
Your observations...
...at a certain time of day...
...in one store...
...in one town...
...in one country...
...means you are able to deduce with certainty whether or not Blu-Ray is growing.
Wow - Nielsen and the other market research firms should be afraid. Small town observation guy is coming to get them!
Seriously - do you not consider that maybe, just maybe, your observations don't tell the whole story?
