In the run-up to MIPTV, Parthenon Entertainment has concluded two major territory deals for Roman Mysteries, including a sale to the lucrative US market.
Stateside, the epic BBC children's drama will air on Rainbow Media's Family Room HD channel from this September.
Parthenon has also sealed a deal in Spain, with commercial channel Cuatro, and is in advanced negotiations with major Italian and French networks.
In Germany, public broadcaster ARD has already bought the series which will also air on the ARD/ZDF-owned German children's channel KI.KA on Saturday afternoons.
"I'm delighted, but not surprised, to announce these two important sales for Roman Mysteries," said Cynthia Kennedy, director of sales and acquisitions at Parthenon. "In the space of six months, the series has sold to, or is in final negotiation with, broadcasters in all the major territories.
"It's testament to the high quality of the show that it has attracted the attention of such key buyers."
Budgeted at £10m for both series, Roman Mysteries is the BBC's largest ever children's drama commission. It is produced by UK production company The Little Entertainment Group, and follows four friends as they struggle to survive through one of history's most turbulent times.
