As she and countless others pointed out, Channel 4 is privately funded, so it doesn’t cost the taxpayer a penny — and yet it is publicly owned, so it must serve regional, minority and niche audiences that would otherwise be ignored. It sources its programmes from independent production companies engaging in precisely the sort of entrepreneurial cut-and-thrust that Margaret Thatcher intended to encourage when she established the channel in 1982. It’s profitable, too: for the past two years Channel 4 has generated a record financial surplus, with revenue of £934m (Netflix is $15bn in debt). And it provides uplift to the British creative industries as a whole. Michaela Coel, Phoebe Waller-Bridge, Jesse Armstrong, Simon Pegg, the most successful British comedy film ever (The Inbetweeners Movie), reality TV, dating and property shows, all developed with the help of C4.
