Delhi- The US$4.5 billion Indian broadcasting sector is gearing up for a war of attrition and only those with courage, capital and content are likely to survive and prosper. That was the key conclusion from the India Digital Networks Summit, held in Delhi on Oct. 17, organized by Media Partners Asia (MPA) and Indian Television Dot Com (ITV). The summit was told that intensifying competition, growing digital pay TV penetration, the launch of hundreds of TV channels and the entry of new investor groups are all going to come at significant cost for media owners, pay TV platforms and advertisers as regulation further squeezes the pricing of television channels, many of which will look to grow and capture their fair share of advertising through significant rate increases. Crucial to the whole equation are the emerging digital cable and satellite platforms which will likely see margins erode in the short term as they look to penetrate a critical mass of consumer homes.
