The copy derived from the Blackhawk print circulated in the 1970s claims this was released as a promotional film in 1922, The Internet Movie Databate claims it was released in 1924.
This was not the first promotional film released by a studio. I have seen one from Bray Studio, HOW ANIMATED CARTOONS ARE MADE, from 1919. What this film makes clear is that Ince was an industrial operation. For the first eight minutes, we get shots of carpenters and other craftsmen and, of course, the Great Man himself -- and a brief bit of Louise Glaum and James Kirkwood performing a scene, but mostly to show off the studio musicians playing to enable them to get in the mood. After the first two-fifths of the movie is done, we get brief bits of some of Ince's stars in the morning routines: Enid Bennett riding horses; Hobart Bosworth painting; Douglas MacLean racing off to the studio, then it's off to work, ending with the film lab and Ince reviewing the previous day's rushes.
It was a massive operation and by 1922, with Ince's production down to a couple of features a year, it was unsustainable. After he died, Inceville was sold to DeMille for his independent company; then it went to the newly-formed RKO, was rented to Selznick, then back to RKO. In the 1940s, Desilu took it over. In 1986, Grant Tinker took it over in a Chapter 11 acquisition. It's changed hands a few times since; in 2014 it was taken over by a private investment group which, as I write this, is supposed to be in the process of being renovated and modernized, a century after Ince first got his hands on the property.
