The document discusses the TRAI's decision to cap commercial advertisements on TV channels at 10 minutes per hour from the previous 25-30 minutes per hour. This is expected to significantly reduce advertising revenue for channels, potentially causing losses of 500-700 crores for the media industry. Small and mid-sized channels will be particularly impacted as they rely heavily on advertising revenue and will face difficulties competing for ads with larger channels that can move excess advertising across multiple channels. The changes may benefit consumers with less interrupted viewing but will hurt small advertisers and create short-term issues for the television industry.
