Sony has four group companies in India: Sony India, for its electronic products, SET - for all television broadcasting, Sony Music India - for all music software, both Indian and western, and Columbia Tri-Star - for movie entertainment.

``The group Website will provide Net surfers a comprehensive taste and feel of the power of Sony in all its diverse yet unified business and consumer interests,'' says the company spokesperson.

Each company has its own Website and the group Website links all the individual sites under one platform. Besides providing links to each individual site, the mother site also gives a corporate profile of each individual company, along with interesting milestones achieved by Sony in various fields. Besides ongoing updates, the site will also host `exciting contests' from time to time.

The mother site takes advantage of cross-traffic between individual company sites and therefore provides a synergistic effect for traffic building through a common platform and domain name. Thus, each individual group company can benefit in terms of cross-traffic across each site and provide advantages in terms of common user profile and in the long run, database sharing, say company sources.
