He explained how various reporters and photographers from the Independent, sister title i, and London Evening Standard, all owned by the Lebedev family, would cover one golf tournament or tennis match.
"We concluded that this was completely mad," Blackhurst said, but admitted that "to journalists this is heresy".
"We can no longer have journalists working in silos," he explained. The integration of the Standard and Independent newsrooms has begun. Business and sport are both now integrated and "there's been no loss of quality", according to Blackhurst.
“I am the fat controller”, Blackhurst added, referencing children's TV programme Thomas the Tank Engine, as he considers his role as one of directing which people go where.
The same journalists will soon be creating video content for London Live, a local TV station which will launch in March.
The TV station is going to run 365 days a year, and the company is currently "hiring TV presenters, make-up people, technicians", and adding 50 new editorial staff to the team.
Journalists are going to write for print, digital and TV, he said. "They are going to be running round with iPhones".
Newspapers are distinguished by editors, commentators and design, Blackhurst said, adding that reporters can provide the same copy for different papers and TV.
"We are freeing people up to do stories they wouldn't otherwise be able to do," he said. And "video is the only way we think that we can make digital pay", he added.
