ABC wants more Shark Tank.

The network has picked up four more episodes of the unscripted series. Combined with the two additional episodes ABC ordered in October, as The Hollywood Reporter first reported, this brings the total order for season five to 28 episodes.

The news comes as the show continues to perform well in the ratings, consistently winning its time period in the 18-49 and 25-54 demos.

Last week's first-run episode averaged 7.5 million viewers and a 2.0 rating among 18-49, doubling its lead-in in the demo. Season to date, Shark Tank has gained 14 percent in 18-49 over the same time last year, marking the show's best performance ever.

Shark Tank, produced by Sony Pictures Television, airs at 9 p.m. Fridays on ABC. In this season, the sharks -- Lori Greiner, Robert Herjavec, Kevin O'Leary, Daymond John, Barbara Corcoran and Mark Cuban -- will offer budding entrepreneurs a total of over $20 million, a series record.
