One word pathetic. While Sony airs almost everything in their regional channels. They keep it to highlights. Why not give Wimbledon and F1 Racing a Bengali or a Tamil feed? They are preventing these sports from growing. They need to more research. Some market like Maharashtra with higher GDP will attract more advertisers than both Telugu state. Yet, they won't give a channel here. Bengali feed can expand operation to Tripura, Orissa and other countries like Bangladesh.
Star Sports does provide many sports events in regional audio/on regional sports channels. Sony has more legroom interms of finances so it can allocate it for different purposes but Star Sports has invested lot on key cricket properties hence is cautious about investing in other areas which will lead to disbalance in financial business model for its sports broadcast business as investment will far exceed revenue generated.
Star Sports infact understands importance of providing sports in regional languages hence has launched regional sports channels and even provides audio feeds on main sports channels for this purpose. Also they spend lot of money for producing customised content/shows for the regional sports audience
