Indian broadcasters care least about graphics and logo. There was some quality during ESPN-Star days, otherwise it's been nothing more than the work of a primary school student. Although Sony have massively improved their Cricket graphics (sleek & elegant) but they still need to work on their logos.
Among foreign broadcasters I think Sky Sports have the best graphics. In terms of logo, ESPN leads the pack in my opinion, followed by Bein, Supersport & Sky NZ.
