A brief reminiscence through marketing history with Pepsi-Cola:
1958 - "Pepsi: For Those Who Think Young."
1963 - "Come Alive! You're in the Pepsi Generation"
1968 - "Taste that Beats the Others Cold"
1970 - "You've Got a Lot to Live, and Pepsi's Got a Lot to Give"
(Unfortunately, this is a different one than the original hippie version, which I can't find :( But the feel is the same!)
1989 - "Simply Irresistable" (Robert Palmer)
Finally, the montage of references to the past, featuring a rather familiar (And now controversial) figure:
2002 - "Millenium/The Joy of Pepsi"
And suddenly, that last commercial makes 100% sense, doesn't it? :)
