* Shifting Market Trends: The DVD market has been in decline for some time, with streaming services like Netflix and Amazon Prime gaining popularity. This may have influenced the decision to stop producing Region 2 DVDs.
* Licensing and Distribution: It's possible that licensing agreements with distributors in Region 2 countries expired, or that the cost of producing and distributing Region 2 DVDs became too high.
* Focus on Digital Releases: There's been a growing trend towards digital distribution of TV shows and movies. This may have led South Park's creators to prioritize digital platforms over physical media.
While there are no official statements confirming the exact reason, it's likely a combination of these factors that led to the discontinuation of Region 2 DVD releases for South Park.
