... hope nobody is surprised.
Companies do this all the time. Its to trick you into thinking its better. It works the other way too. Candy companies sell "NEW MINI" versions of their products that are the same but have less content. Soda companies create new bottles that hold less but cost the same. And quite often, cereal companies will re-brand the same cereal as a new product using a different name and logo.
ALSO re: lays
Walkers is the original, started in 1880 apparently. It was an independent UK company but was later taken over by PepsiCo and adopted Lays logo etc. Lays came into existence in 1930ish.
