In a note to clients last July, the media analysts Enders suggested strong profitability in 2023 could justify a valuation of £740m for The Telegraph alone, implying that a package with The Spectator could be worth £800m. In the immediate aftermath of its raid on last year’s auction, RedBird IMI won praise in US media circles for bagging the pair for only £600m.

The precise form of the scheme that will be chosen remains to be specified, as some analysts, such as François Godard at the British firm Enders Analysis, imagine the creation of a local entity that would be listed in the country. In any case, the pay-TV channel confirmed its intention to maintain a listing in Johannesburg, "so that South African investors can benefit from the future growth of the company," the statement said.

“It is in decline,” said Tom Harrington, the head of television at the research firm Enders Analysis. “Viewership numbers are pushed up by older people, who only watch broadcast television, and watch a lot of it.”

That decline is not the whole picture, though, Harrington said. “People still spend more time watching linear television than they spend doing anything else, except sleep and work,” he said. “It still commands an enormous amount of attention.”

The greater change, Harrington said, was in the “communality” of the experience: We consume more content than ever, but we tend to do it on our own. That means there is less overlap between what young people watch and what older generations do. “Those touch points have been lost,” he said. “And that means there is a lack of common culture, which is a little bit sad.”

"Peltz is an unusual character because what he's doing is going around to multiple companies and saying ‘I'm going to fix the show,'" says senior media entertainment analyst Gareth Sutcliffe from Enders Analysis.

"But the key point is an activist investor is only as good as the questions that they are asking of the board.

"And I think that the key point is that you want to have nominees who clearly have a background and experience and are helpful in terms of moving a company forward to the next stage."

"You cannot underestimate the level of interest there is in a company like Disney and the fact that people always think that they have the best ideas," Mr Sutcliffe said.
