Twitter: Breaking the Bird
9pm, BBC Two
“This is the stupidest thing ever.” That was a common reaction to Twitter in 2006, according to the San Francisco startup’s “ragtag” founders who created it in just under two weeks. They give their input on the social media platform’s legacy in this documentary (Jack Dorsey, who stepped down as CEO and sold it to Elon Musk in 2022 is noticeably absent), along with former employees, journalists and activists. While Musk’s renamed X may be a hellscape today – and it has been hugely damaging to society – there is plenty of good to be found in its history. All the highs, lows and grey areas are laid out here, including the revelation that Oprah didn’t actually type her first tweet. Hollie Richardson

The trip is less than three weeks long – surely they can resist the temptation to phone home? Jack Seale
The White Lotus
9pm, Sky Atlantic
The deluxe Thai vacation is almost over, as Mike White’s savage satire reaches its penultimate episode. Despite all the infidelity, drugs and incest-adjacent stuff, no one has died in season three yet.
