I want to know the answer to the following question:
When were ski-lifts built in Swiss and Austrian towns?
All the background I'm provided with is that "During the post-World War I period ski-lifts were built in Swiss and Austrian towns to accommodate winter visitors, but summer tourism continued to be important; by the mid-20th century the popularity of downhill skiing increased greatly as it became more accessible and in the 1970s several new villages were built in France devoted almost exclusively to skiing, such as Les Menuires.". Is that enough to answer the question?
Answer: yes
