Pepsi is in the market from that time when I was born. I used to drink pepsi from my childhood. But product has to be change with time , its taste is same as it was many years ago. The second thing is that its variety , product should have many flavours and it should keep changing with time , but with pepsi it is not so. Its logo also does not change with time but it is ok. Advertisement is also a good thing for popularity , but pepsi do advertisement sometimes and sometimes it gone. All over , it does not produce an effect on me.
