Advertising giant Google has been revealed to have deliberately used a flawed study in an effort to make its Nexus 7 tablet look more popular. During the launch of the latest Nexus 7, a Google executive showed figures that "proved" that the Nexus 7 was the most popular tablet in Japan, outselling the iPad. This has now been debunked with the revelation that the study by Japanese market research firm BCN did not include iPad sales from any of Japan's seven Apple Stores, its two largest telecom partners, or Apple's direct online channel.
