For example if it is a music channel you can advertise it in music magazines and sites.\n\nYou need to disclosure more information about your TV channel to get better answers…\n\nGenerally, I suggest you advertise it in newspapers, magazines, and billboards (not radio).\nIf TV channels in your region or country are plenty you may need to segment the market you are targeting at, so that you are differentiated (creating advantages and adding value for your clients).\n\nDo market research… See how your idea sounds to people? Listen to what they need… you may get proposals on what type of channel is missing in your town or what type of channel they want.\n\nBear in mind that a TV channel is a big investment and you need to carefully plan all your steps and actions.
