Why are TV channels not working on online broadcasting?

Question

Computer networks

Actually the question is very simple. Why is the online broadcasting of an absolute number of TV channels has a large clipping in the fields, rather low quality (even when choosing the HD format) and has a lot of lags. Some channels additionally embed an advertising module into the player before the start, which is also not clear to me.
If they all make money from advertising on the air, what difference does it make where to show the air itself on the Internet or by wire?

Answer 1

There are nuances) And advertising is far from the only way to earn money.
Each channel, providing content, has an agreement to show it to a certain number of users through a certain transmission medium. And as a rule, the Internet is not included in the list of transmission media in agreements with copyright holders. This is especially true for sports broadcasts.
On the other hand, each television provider, whether it be terrestrial, cable, satellite or ip, also has agreements with each channel (directly or through content aggregators), taking into account also the transmission medium and the number of subscribers. The Internet does not pay TV channels to show their programs, but ISPs do.
This is true... and the channels also have exclusive agreements for a number of programs with content aggregators, with new programs gaining popularity that do not want to be broadcast via the Internet, with Russian cinema that does not want to distribute their films via the Internet, especially in HD quality ..
From this it follows that broadcasting via the Internet is simply unprofitable

Answer 2

It's probably a matter of conservatism. The Internet is full of pirates and all that.

Answer 3

The answer is simple: why?
This is an additional infrastructure that needs to be maintained, these are your programmers who want 150 thousand salaries and all that.
And at the exit, the profit will be minimal, because. a significant part of Internet users will download torrents and watch the same thing, but without ads, and the second part will already be recruited by existing online cinemas.
Moreover, in the Internet environment, a model with THIS amount of advertising that is on TV is simply not viable, it is easier for a user to buy a subscription for 300 rubles per month than to watch 5 minutes of advertising every 10 minutes.
TV is now a very conservative area, because "everything works anyway", brings a lot of dough and why change something?
