My wording is the other way around. I need the qualifier "dominicana" to designate the authentic version.
That’s a very European thing which we don’t find or use in the USA. Salsa Cubana, Salsa Linea, Bachata Dominicana, etc. Here it is Casino, Cuban salsa. NY style, on2, LA style, on1, Bachata etc.
In the USA when bachata first started getting popular it was very simple side to side close hold dance. No one taught it. You saw others do it and copy it. Then some salsa instructors started forming bachata performance teams. It gave them additional students. Bachata performance choreographies borrowed moves from salsa and fit it to the rhythm of bachata music. That’s how moves got introduced into the bachata dancing.
Then some instructors started emphasizing on independent footwork to the fast bachata rhythm. This in the USA started getting called as Dominican Bachata.
While in DR itself the bachata dancing was simple and sprinkled with footwork depending on the music. When instructors in the USA claimed they were teaching “authentic” bachata as danced in DR, many sneered.
Most dancers in the USA still dance bachata as simple side to side with may be a few turns. Some who learnt footwork or can do it mostly came from salsa background at that time. They learnt Dominican bachata footwork at classes and workshops.
Later sensual in Europe took a whole different path. Sensual is a learnt dance. It appeals to many youngsters who find salsa difficult.
Here, zouk was an absolutely new creation without substantial contact with the brazilian or lusitanian communities.
Zouk started getting popular in Europe around 2007/8. It wasn’t led by Brazilians and differed from Brazilian zouk.
In the USA hardly any social dancers came to zouk, kizomba or bachata from ballroom world. Those dances were poaching dancers from the salsa scene. Some salsa studios and instructors started offering these as a way to increase their students numbers (and hence make more money). This all started in late 2000s. They also started attracting a lot of first timers to the partner dancing. Salsa was and is still huge in the USA. It is also fragmented between by various styles, learnt and vernacular dancers.
There's a long-established kizomba scene among angolese immigrants in my city. They stayed among themselves. However, many local followers who failed in ballroom, salsa or other partner dances find refuge in the kizomba scene.
Kizomba in Europe is now its own scene. Mainly centered around Paris. The women love it. There are 3 women for every one man in Kizomba out there. People will dance with each other for 30 minutes, an hour or two hours without changing partners. Minimum 15-20 minutes is the norm. I have noticed a certain type of people get attracted to the Kizomba scene (not same as dancing Kizomba).
What you didn't mention is that forró is currently taking off.
It has tried to take off multiple times. Yet never reached the critical mass or escape velocity.
I am no longer plugged into various different dance scenes.
