i am trying to start a blu ray dvd player reviews blog on comanies patent products like sony, panasonic or like these companies... i want to ask that can i put their products details from their site to my blog with "courtesy" or "source" tags and links to that posts from my blog? is it illegal activity or can i use it on my site? and google makes my blog suppliment?
I don't think its really a good idea to focus a blog around stealing content, even if you do give credit. In the end you won't have a lot of unique content. You are better off writing about each product in your own words. Also I don't think too many of the manufacturers would approve you using their content.
