On 18 January 2011, at 11:00 p.m., Polskie Radio Program IV officially started the project Radio na Wizji.[3] It is a television channel, broadcasting as live video feed of the PR4. It's similar project to Italian RTL 102,5 Very Normal People, but the product of Polskie Radio is more advanced.[3] However, due to very low watching figures the broadcast was announced to close at October 2011 (on satellite), while all cable serviced slowly follows.
