"Casting couch does exit in TV industry, those who says that they have not encountered it; they are lying. Everybody goes through that but doesn't want to confess about it. In TV industry, it you are not doing a favor, then you are surely not getting a good role. It starts from a minor to major level. There are few coordinators who promise you to give role of bahu; on the screen but ask you to wear a bikini for the audition. In fact, there are few bold coordinators also who directly says that he/she has to satisfy his client for a lead role.
People do fall in such kind of trap nut it's the glamour which doesn't allow them to take understand what is right or wrong. Personally, I too have been a victim of casting couch where I was asked a favor to please three men. Thankfully, I was bold enough to walk out of the situation"
