Thorne's paranormal drama was cancelled following a single series, with the writer blaming "massive cutbacks" at BBC Three.
"When it came down to it, it was between Being Human and The Fades [to be kept] and they chose Being Human," he told A Younger Theatre.
"I can't complain because it is a great show. It happened when there were massive cutbacks, so the drama budget [at BBC Three] was halved and they could only keep one long-running series."
Being Human was ultimately picked up for a fifth series in March.
Regarding the future of The Fades, Thorne added that "there is a possibility" the show could still return, following its BAFTA win last month.
"I don't know what's going to happen," he admitted. "I'd love for it to come back, as I've still got stories to tell."
The Fades star Joe Dempsie recently told Digital Spy that he was disappointed the show failed to secure a second series.
"I thought a programme like that really was a chance for a channel like BBC Three to move away from My Boob Job and Me [-type shows] and a lot of the stuff that you usually identify with them," said Dempsie.
"I don't know if maybe that was part of the problem - if people don't know that good drama lurks on BBC Three, they're not going to find out about it."
