The new service will mean that audiences will be able to watch streamed programmes when they want on the BBC Three and catch up on any they have missed.
'The Mighty Boosh' series will be broadcast online from July 19, a week ahead of its television transmission on July 26. All episodes will be available to view for up to seven days after the final programme of the series transmits on BBC Three.
Jana Bennett, the BBC's director of television, said: "The broadband premiere of 'The Mighty Boosh' is a significant step forward in offering our audiences even greater value in a changing television world."
The show, which is produced by Steve Coogan and Henry Normal's Baby Cow Productions, centres around the adventures of two zoo keepers, Howard Moon and Vince Noir. The pair work at The Zooniverse, a magical zoo run by Bob Fossil. The first series was shown last year on BBC Three and subsequently BBC Two.
Julian Barratt and Noel Fielding play the zookeepers, who battle with Zooniverse owner Dixon Bainbridge, played by Matt Berry, and zoo manager Fossil, played by Rich Fulcher.
The broadband premiere of 'The Mighty Boosh' follows BBC Three's Sunday night 'Best of Three' multiscreen trial, which was launched in May and continues for six months.
On Sunday nights from 9pm, digital satellite viewers are prompted to press the red button and are offered the choice of three of their favourite BBC Three programmes, in addition to the channel's live transmission.
The new service comes as Ofcom revealed in January that 6m households in the UK have broadband connections.
