Sky TV's director of entertainment channels wants to create a show with the ambition and scale of US dramas such as Game of Thrones and Band of Brothers.
In a blog about the future of Sky's entertainment offering, Stuart Murphy said that the channel is "actively looking" for a series that could raise the bar for British television.
He wrote: "We've been talking a lot about how we can supersize what we do. Of course Sky is fundamentally different to other broadcasters because of its relationship with its viewers. When you pay for something, your expectations are higher.
"As a company, we are in service of our customers. We deliver what they want - and they tell us they want something different and special.
"So as part of that vision, we are now actively looking for a new drama commission of real scale and huge ambition.
"A drama with humour and emotion, big budgets, huge sets and A-list talent. Others call them 'landmark dramas' or 'tentpole'. We simply call them 'game-changing dramas'. This will be our Game of Thrones, our Band of Brothers."
