KARACHI (PR) - Pepsi Pakistan recently launched their new thematic campaign 'Badal Dou Zamana. In this campaign Pepsi brings out the undying spirit of optimism and positive thinking in the Pakistani youth that keeps them going against all hardships to attain their goal. For this particular campaign, Pepsi has taken on board three new brand ambassadors: Aisamul Haq Qureshi, who has emerged as Asias top ranking tennis player, winning countless tournaments, even beating the world champion, Roger Federer recently. In a country where cricket is followed to the verge of being worshipped, Aisam held on to his dream of achieving excellence in tennis by devoting so far, his 17 years, mostly away from his home and family in Lahore doing tough professional training. These are the years young boys of his age usually spend enjoying life and taking it easy but Aisam is determined to excel further and promote tennis in Pakistan. With this campaign bringing his talent and remarkable style to the limelight and to the attention of millions of youngsters, this is bound to happen. The other phenomenal sportsman to appear in the commercial alongside Qureshi is Mohammad Amer, the youngest, fierce fast bowler in the Pakistan cricket team who has already made it to the Twenty20 World Cup before his 18th birthday. In a short span of three years of which almost half he had to spend outside the field due to a serious back injury and once dangue fever, Amer kept his spirits high and not only bagged wickets of players like Tendulker, Ponting and Dilshan, but has made the world record as the highest scorer of a number 10 batsman already. He hails from a small town in Punjab but his dreams and visions are much bigger. His advice to his fellow youth is to rise above all shortcomings and negative thinking and focus on their talent. The third Pepsi brand ambassador for this campaign is not an individual but an alternative rock band Call who have in the recent years come up as the voice of Pakistani youth and also won hearts across the border with their hit songs like Shayed, Sab bhula ke and Laree chootee. Call has not only endorsed this campaign but also given words and voice to the message 'Badal Dou Zamana. 'This message is very close to our heart they say, as it reflects the spirited message of keeping the faith in ones inner strength and capabilities, the philosophy Calls music revolves around.
