This is exactly what i have been saying from the start: if they merge both apps, i hope it will be under the DPHS which they can then rename to JioHotstar or JioStar. They could organize the content into sections like Star, Colors, JioHotstar Originals, Disney+, Marvel, Anime, Kdramas, HBO, News, Movies and more.
If they choose to keep two apps running separately, I’m curious about what they would offer for free on JioCinema besides the trashy soap operas. Maybe Bigg Boss would be a good fit but i doubt IPL would make sense to stream for free.
IPL is a major property that needs both subscription and ad based revenue (from TV as well as OTT). So the better solution would be to merge everything into DPHS, rename it JioHotstar or JioStar, whatever they prefer and offer both SVoD and AVoD services.
