In Germany, there is a law that regulates the amount and intervals of advertising for private television broadcasters: 20% or 1/5 per broadcast day may be used for advertising. Programs that are shorter than 30 minutes may have a break, otherwise there must be 20 minutes between commercial breaks - 30 minutes in the evening. Unfortunately, there are still some loopholes.
Children's programs are not allowed to have commercial breaks.
It's a shame that this law still doesn't apply to YouTube.
Maybe they want to compete with the price per subscription: let's say they want to charge 5 € per month for Photo, Design and Publisher each, against 26 € for Photoshop (alone).
Remembering the situation when Macromedia was bought bei Adobe – now I have the same vibes again. Five years later nothing was left except Flash – that horrible piece of software – and Dreamweaver – I liked that one. The best transition back then was from Freehand to Illustrator and (consequently from Quark) to InDesign.
And then in 2015 to Affinity. So ... 5 years with Corel, 12 years with Adobe/Macromedia, now 8 years with Affinity, so far ... let's see what they do and what we decide afterwards.
With the WebM-Format they use it might be possible. It's based on Matroska and there is a feature to replace or add chunks within the stream in realtime.
