The former Good Morning Britain presenter also comfortably beat Andrew Neil’s launch show on GB News on June 13 that secured a peak viewership of 336,000 viewers.
However, the rest of TalkTV’s slate fell short of its rivals on launch night.
The News Desk with Tom Newton-Dunn had an average audience of 54,200 in the 7pm slot, compared to the GB News show helmed by Nigel Farage, which secured 71,500.
BBC News and Sky News also delivered a respective 136,600 and 133,200 for the hour.
The Talk with Sharon Osbourne also trailed TalkTV’s major rivals. The show reached an average audience of 43,900 between 9pm and 10pm, compared to GB News’ 62,700, BBC News’ 113,900 and Sky News’ 56,700.
Mr Morgan’s performance provides a strong footing for Rupert Murdoch’s insurgent channel to build upon, as it attempts to disrupt the BBC with a US-style brand of opinionated news.
His comments have also laid the foundations for a heated rivalry with GB News, the start-up attempting to disrupt British broadcasting with its unique brand of opinion-led news.
In a tweet, Mr Morgan referred to Mr Farage’s attempts to derail TalkTV’s interview with the former US president by handing him a dossier of critical comments made by the ex News of the World editor.
