There are a lot more 16mm films made than there are either features produced in the "H" place or for TV. In the fields of documentaria, especially scientific and nature programing, 16mm is the prefered media. If you are spending 3 months on an ice flow in antarctica filming penguins or in the Gobi desert documenting archaelogical excavations, or even in a lab doing timelapse of developing embryos 16mm is the better way. The main problem with electronic media is that they have a constant demand for electricity which is not always available or of good enough quality. A 16mm clockwork drive can run just about everywhere. This is one of the reasons that clockwork edison cylinder audio recorders were in wide use until the late 1970s by anthropologists. It was only with the introduction a cheap solar and small portable generating sets that the cassette recorder became more popular. If you are in the middle of Borneo you do not want to have to carry 600 lbs of batteries. The same principles apply to movie making. Also the quality of the image is much better than you can ever get on video.
