A campaign to save Star Trek spin-off show Enterprise says it has received a $3m (£1.6m) donation from anonymous figures in the space flight industry.
Fans want to raise enough money to fund a fifth series of Enterprise
TrekUnited, which is trying to raise money to make another series of Enterprise, says it has a "legally binding pledge" from three donors.
TrekUnited said the donors were "some of the main entrepreneurs in the commercial space flight industry".
They did not want to be named but said they had been inspired by Star Trek.
In a statement on the campaign's website, the three donors said Star Trek had inspired at least half of their colleagues to work in the space industry.
A month ago, TV channel UPN announced that it was cancelling the show after four series.
Enterprise stars former Quantum Leap actor Scott Bakula as Captain Archer and is set before the original 1960s Star Trek series.
The donors said: "Enterprise needs to be renewed for the sake of fan loyalty, for being quality TV, for bringing imagination and hope for a better future to our homes.
"But over all that for inspiring us so strongly that we have fought all our adult lives to bring that future closer to our children and to us."
Fans have held rallies in cities including Los Angeles
A TrekUnited spokesperson said they knew the identities of the benefactors and they were satisfied they were genuine.
The spokesperson said it would take just under $30m (£15.7m) to pay for a new series and they were trying to raise as much as it took to allow a broadcaster to keep the series alive.
Campaign supporters have already staged rallies around the world in an attempt to convince UPN's parent company Paramount to reconsider its decision or persuade another media company to take over the show.
The campaign's fighting fund stood at $3,072,685 (£1,606,845) at 1700 GMT on Wednesday.
