How much is the screencast service (ala livecoding in good years) in demand for programmers?

Question

Video broadcast

A few years ago I sat on a wonderful livecoding, at some point the format in which they worked was bent and, apparently, the problem was in the large resources consumed for this kind of project.
In an attempt to find a similar alternative where the required contingent is also concentrated, alas, I did not find it.
From time to time I pick this direction, I raised a small api with a service for streaming as a test, I have an idea to write a similar product, there are resources to start, I have not built plans for further content and business strategies.
The question is extremely simple, how much this product is in demand and relevant, whether it will be enough to fill the project with off-line content to attract an audience (with the ability to stream).

Answer 1

There is twitch
there is youtube there
is fb
there is also bullshit from ms
you will need god level marketing, because everything below twitch could not fit into this niche
