The new short-form streaming service Quibi, which debuted April 6, was meant to be ideal for smartphone users on the go. But now that no one’s going anywhere, what’s the main attraction?

For now the answer is content and celebrities — and oodles of both.

Quibi stands for “quick bites,” which refers to the service’s plan to offer short video segments (10 minutes or less) designed for small screens (your phone). But little else about Quibi is bite-size. In its first year, the company’s partners (the chairman Jeffrey Katzenberg and the C.E.O. Meg Whitman) are spending more than a billion dollars on content acquisition alone.

That’s partly because everyone in Hollywood seems to be doing a Quibi show, including heavy-hitters like Steven Spielberg, Guillermo del Toro, Kevin Hart and Jennifer Lopez. Its debut lineup already consisted of more than 40 shows, including Liam Hemsworth’s “Most Dangerous Game,” Queen Latifah’s “When the Streetlights Go On” and Chrissy Teigen’s “Chrissy’s Court.”

But that is just a fraction of what Quibi says it will release in its first year: about 8,500 “quick bites of content” and around 175 new shows. Thirty-five of these shows will be “movies in chapters”; 120 will be unscripted reality shows or documentaries; and the rest will be news and lifestyle pieces, or what they call “daily essentials.”
