The ABC is planning to repeat the series Paper Giants: The Birth of Cleo due to the success of the first screening.

The two-part series became the highest-rating program on ABC1 this year when it aired earlier this week.

On Sunday night, part one won its timeslot with a five-city average audience of 1.2 million.

On Monday, the second part also won its timeslot with an average audience of 1.34 million.

"We had hoped that Paper Giants would appeal to a wide audience and we are thrilled they have not only taken one bite, but came back in greater numbers for second helpings on Monday night," ABC1 controller Brendan Dahill said.

"But for us, it isn't about ratings. We screened Paper Giants outside the official ratings period so the Australian audience had something to look forward to when the commercial networks were taking a break."

The program, which stars Asher Keddie as magazine queen Ita Buttrose, will air again on Easter Sunday on ABC2.

The show also stars Rob Carlton as Kerry Packer and Tony Barry as Sir Frank Packer.
