PARK CITY, Utah >> Even in the streaming and video-on-demand age, independent films are still judged by their performance at the box office. And by that measure, fewer and fewer are crossing into the mainstream.

More than 1,100 movies have had their premieres at the Sundance Film Festival over the past decade, but only one has managed to cross the $40 million mark at domestic theaters. “Precious: Based on the Novel ‘Push’ by Sapphire” took in about $53 million in 2009, after adjusting for inflation.

Even that result was modest, compared with films of the past. In 2006, the Sundance gem “Little Miss Sunshine” collected $71 million. Another Sundance discovery, “Saw,” hit $72 million in 2004.

Most Sundance films these days are lucky to earn six figures at the box office — in total. For instance, the comedy “Wiener-Dog,” a follow-up to the 1995 indie hit “Welcome to the Dollhouse,” collected $470,575 last summer before arriving on Amazon.

Have streaming and video on demand made up the art-house slack? Or even broadened the audience? Nobody really knows. Most distributors refuse to make that viewership data public, in part because they don’t want filmmakers and their agents to be able to use the information to demand a bigger paycheck.

So ticket sales remain the yardstick. As another Sundance begins — the 33rd installment runs through Jan. 29 — here is a look at how some selections from last year fared.

‘SWISS ARMY MAN’

Sundance loves to push buttons and champion artistic choices over commercial ones. Nothing sums up that ethos better than this drama, which stars Daniel Radcliffe as an extremely flatulent corpse. A24 took a flier on it nonetheless, buying the rights for a reported “low seven figures,” in part to start a relationship with the film’s young directors, a duo known as the Daniels. (That would be Dan Kwan and Daniel Scheinert.) The movie sold about $4.2 million in tickets.

‘MANCHESTER BY THE SEA’

Some distributors turned up their noses at this hard-bitten drama, saying it was too long. But Amazon and Roadside Attractions swooped in and grabbed the 2-hour-17-minute film for about $10 million, powering it to about $37.4 million in ticket sales over three months. “Manchester,” starring Casey Affleck and Michelle Williams, could get a second wind on Jan. 24 in the form of Oscar nominations and join “Precious” as a true breakout hit.

‘THE BIRTH OF A NATION’

One of the biggest implosions in Sundance history, Fox Searchlight paid a record $17.5 million to buy this violent drama about a slave rebellion, which was instantly heralded as a masterpiece by film insiders desperate to end the #OscarsSoWhite firestorm. But the creative force behind the film, Nate Parker, soon faced harsh scrutiny about a sexual assault allegation in his past, and audiences, particularly black women, abandoned the film. The movie collected $15.9 million.

‘HUNT FOR THE WILDERPEOPLE’

An adventure about an unruly boy and his foster uncle, this film has beaten the Sundance odds, taking in $5.2 million over 19 weeks. The Orchard, owned by Sony, paid about $2 million for the rights. The Orchard is one of the very few film companies that discloses so-called ancillary revenue (video on demand and whatnot), and “Wilderpeople,” directed by Taika Waititi, has about $5.7 million (and counting) in that column.

Still, more people will see Waititi’s next film, the Marvel-Disney action adventure “Thor: Ragnarok,” in November in its first few hours of release.
