Modern Wicca originated in the United Kingdom (i.e. Great Britain/The British Isles) in the late 1920's and early 1930's. It wasn't brought over to the U.S. until the late 1960's and early 1970's most notably by Wiccan author Raymond Buckland. So, no, it wasn't particularly popular at that time. It isn't exactly "big", now, for that matter, when compared to other religions, such as Christianity or Buddhism... even though it is a rapidly growing religion; it is still quite in a state of infancy... in other words, it is not currently a mainstream religion.
Georgian Wicca was created in 1970.

When a person celebrates Wicca, they are celebrating their faith within it. Wicca is not only a religion, but it's a way of living, and most Wiccan's actually celebrate Wicca every day they are part of it.
There is nothing called Dark Wicca. Wicca is a religion, it is neither Dark or Light.. There are mysteries in the craft of Wicca, and the unworthy would use it for dark purposes. That is why there is a degree system in Wicca, where the secrets are revealed only to the worthy. Wicca is about life and earth and magic. It is up to the individual to decide what they shall attain in their life time.
Wicca is Polytheistic. Believing in many Deities/Gods
