I don't really know how many movies Public Movies has bought... Sun Network is a freak in acquiring movie rights and almost 70% of Kannada Movies are in Udaya's Library. They can start four to five separate channels for very-old movies, old movies, new movies and very-new movies.
However, Colors, Zee and Star Suvarna all put together, have 20-25% rights. Kasturi somehow acquired some very-old movies from Udaya and they have 5-10 new movies, not very new though. Zee should just acquire Kasturi (which is not possible) and rename it Zee Cinema Kannada. Suvarna should stop airing sports on Suvarna Plus (which will be possible after Star Sports Kannada is launched) and make it a full-time movie channel. They also should rename it as Suvarna Movies instead of Plus. Colors focus is on shows and content, they can stay with that with occasional movies on both their channels.
