PEPSI question

Why is it that the older bottles of Pepsi had the rights reserved symbol after the second “P” and now it’s after the entire word? If this has been covered before please link me to the topic. Tank you!

It’s “regestered trademark”.

Uh, yeah that’s what I meant. But does this mean no one knows the reasoning behind the placement of the little R? Come on! Someone knows a relative or a friend that works with Pepsi Co.!!!

Are the two “PEPSI” symbols identical? It’s possible that the company was protecting a certain aspect of one design.
