Pepsi rebrand " How effective is it"

Pepsi, when I think of Pepsi some of their past designs come into mind as well as slogans. For example   some of the best slogans Pepsi used are:

"Say pepsi, Please,” “For those who think Young,” “The Pepsi Generation,” “Taste That Beats the Others Cold” These are some of the classic logos and slogans for the worlds 2nd best soft drink. During the past century, Pepsi has produced an image of fresh, youthful energy. The circle logo is iconic and began as a 1930′s-era bottle cap, with its red, white and blue color scheme in 1941 which began to help support of the war effort, and in 1962 made the leap to the bold, sans-serif typeface that     has been used ever since.

It was the 1962 typography that changed the visual idea and helped to separated Pepsi-Cola from Coca-Cola, which until then had been sharing the same, Spencerian script, at least in the uppercase letters. Pepsi’s clean, modern look was in sync with 1960s design, in which sans-serif type had began to receive huge popularity, and for a time it left Coca-Cola’s 19th-century logo looking rather old.

With Pepsi's current logo i believe with out the type it leave a boring plain effect. the type is what can sometime make or break the popularity of the logo. But in saying that the iconic circle with the red, blu and white, is known and society can establish the connection to Pepsi. Also the circle is very close to the color scheme and shape of well known basketball logos.
