**Channel 4**, officially the Channel Four Television Corporation, is a British state-owned, commercially funded public-service broadcaster that operates 12 television channels, the UK's largest free streaming service, and film/TV production arms like Film4.[1][2] Launched on November 2, 1982, as the UK's fourth national TV service, it complemented the BBC's license-funded channels and ITV's commercial network. Unlike the BBC, Channel 4 receives no public funding, relying entirely on advertising and commercial revenues to maintain independence.[1] Headquartered in London with a national base in Leeds and creative hubs elsewhere, it functions as a publisher-broadcaster, commissioning content from around 300 independent UK producers annually.[2][4] Its remit emphasizes championing unheard voices, bold risks, diversity, and reinventing entertainment to spark national conversations.[1][2] Key achievements include pioneering on-demand TV with 4oD (later All 4) in 2006—the first UK broadcaster to do so—now boasting 28 million monthly video views and 7.6 million unique users.[3] E4, launched in 2001 for 16-34-year-olds, boosted its youth appeal with US imports and extended shows like *Big Brother*.[1] Film4 has earned 43 Oscars and 97 BAFTAs, backing British filmmakers.[2] Channel 4 News holds a fixed 7pm weekday slot, delivering daily bulletins.[1] Currently, it runs channels like Channel 4 (main public-service network), E4, More4, and others via The Box Plus Network, plus streaming and radio ventures.[1][2] It claims the youngest-skewing public-service audience, outpacing commercial rivals among 16-34s across TV and streaming.[2] Technologically, a 2020s network upgrade with Exponential-e enabled resilient, low-latency multi-platform delivery, ditching tapes for automated workflows an
