Airports have started catering to international flights more in the 1930s than a decade before when they focused more on regional and municipal travels. This enabled people to travel the world for pleasure or work. With the development of airports and international travel, tourism also flourished - hotels, restaurants, etc. began sprouting up everywhere to attract tourists and travelers.
The automobile industry grew rapidly as well - one example would be Henry Ford's Model T because it was affordable, and therefore mass-produced so many people could have it.
The US started focusing on building more freeways as that is the most popular way to transport goods within the country. In the past, roads were used but with the 'invention' of more practical ways of transportation, this process was sped up.
In other parts of the world, like the UK, the first subway systems appeared, namely, London Underground in 1863. This saved the city from automobile congestions and transferred part of its travel underground.
And there are many other great inventions and improvements to come in the future.
