Segment the young in India and you get three kinds. The Hindi, Hinglish, and English. The first kind, mostly found in towns and villages (north of India) take to Hindi, lock, stock, and barrel. The second, the 'Hinglish' crowd populates towns and metros. They oscillate between, and integrate Hindi and English to suit them. This is the 'going on dude' crowd that inadvertently or knowingly peppers English with large doses of Hindi, or the other way round. The final bunch is the convent educated, metro crowd. They are the 'dude' crowd. They frequent cafes, sport sneakers, swear by denims, and pretty much are clued into everything digital.
The young pose the biggest interest to marketers. In addition to being large in numbers, the young don't hold back on consuming, and because it'll be while before they kick the bucket, the moolah marketers can extricate from them (read, customer lifetime value) can be quite a sum.
Featured above are two commercials from Telecom companies, one's for the 'Hinglish' crowd, the other targets the 'English'.
