I've seen in many websites that these exists a part called "footer" at bottom of the page and there's a sentence written on it.
All rights reserved.
I know what it means. But everytime i read that, i have a feeling like this : "Who reserved it?" and i always had doubt about this sentence :
All rights reserved by company X.
Is this one wrong ? If yes, why? If no, why i see the first sentence everywhere?
