Travel back in time to San Francisco: April 14, 1906, 4 days before the earthquake

That’s fascinating, and I learned a lot. Thanks!

The 1906 San Francisco film wasn’t filmed for Hale’s Tours, though. The Miles Brothers–there were four, two of whom made the movie in the OP–were a big deal in their own right:

The first movie studio on the West Coast, built and operated by the Miles brothers, was also destroyed, debilitating San Francisco as a film production center and forever changing the industry.

In those early days, films were sold outright to theaters, but it wasn’t until exhibitors could rent films that theaters became a profitable business. One of the first companies to establish a film rental exchange office was Miles Brothers. Harry, Herbert, Earle and Joe Miles set up shop in the spring of 1903, importing films from Europe and buying from the five film producers then in the United States. The Miles Brothers soon established a national reputation, expanding to New York later that year and becoming the first film exchange company to operate from coast to coast.

I think the answer to your question:

is “The miles Brothers, because in those very early days, moving pictures were so fascinating in and of themselves, people would pay to see footage shot from a cable car.”

That’s a fascinating film.
I had seen the original version,in black-and white, and silent. But the colorization and added sound track makes it even more realistic. It shows a genuine and realistic view of daily life…so chaotic, lots of dangerous near-misses…all so different than our lives today.

And so, since it’s so real… I’m gonna raise another issue about realism(and I wonder if I’m the only one who thought of this): sanitation.
Well, actually…I’m talking 'bout is : horse shit. And the lack thereof in this movie.

I have read reports that major cities everywhere in those days were reeling under the huge quantities of shit that was inevitable in the days of horse power. https://www.historic-uk.com/HistoryUK/HistoryofBritain/Great-Horse-Manure-Crisis-of-1894/

But in this film clip…there are lots of horses, yet the streets seem pretty clean.
What’s up?

Street Sweepers. A lot of 'em

Actually, your own cite says that the footage WAS shot for Hale’s Tours:

D’oh! I don’t know how I missed that after reading the article twice. Thanks much for the correction!

I’m pretty sure some of the nondescript debris on the ground is house manure, but you can actually see one street sweeper doing their thing around 1:20.

There is that school of thought, but I’m not convinced.

From that link: “By 1912, this seemingly insurmountable problem had been resolved; in cities all around the globe, horses had been replaced and now motorised vehicles were the main source of transport and carriage.”

At first, I read that as “…now motorised vehicles were the main source of transport and carnage.”

You may have misread it, but you’re not wrong:

I just watched the last part of the video. I love the fish-eye the dame in the elaborate hat gives the streetcar camera as it approaches.

She does not strike me as the sort of person who appreciated modern documentary techniques.
