Fox Corp. revealed new details about its streaming service on Monday, including that it would debut this fall and would be called Fox One.

The announcement came ahead of the company’s upfront, an annual pitch to entice advertisers with a slate of upcoming shows. Lachlan Murdoch, the company’s chief executive and son of the Fox Corp. founder, Rupert Murdoch, previewed the service on a quarterly earnings call. The name Fox One, he said, was a reference to the combined heft of the company’s TV shows, cable channels and broadcast network, including National Football League games.

“Whether it’s the Super Bowl, the election cycle or the upfront, our company is at its best when we work together as one,” Mr. Murdoch said.
