Why the sudden change? On the one hand it ties to the parent brand. On the other hand DSport was clearly established as an Indian channel. Maybe they wanted to change the name because of the failed association with Lex Sportel Vision and neither party wanted to continue with the DSport name.
Discovery Communications is the parent of Eurosport. It has better brand value than Dsport. Moreover, Discovery Channel is better known for factual programs than sports. So, renaming the channel matters in the board meetings and decision making of the company and future alignment of the portfolio in various segments and
regions .
