skyscrapers seem like a very new idea. but in fast the fist one was built in 1884 in chicago. it had nine floors.
as skyscrapers have many floors. their owners can get more rent. so the empire state building in new york was finished. it was the tallest building in the world until 1970. with 102 stories . then the world trade center with 110 floors .was built agin in new york. after that in 1974. the sears tower was built in chicago. it also has 110 floors . but it is higher than the world trade center. the tallest building in bangkok-baiyoke II-is only 90 stories high.
sometimes too many skyscrapers are built. so there are not enough people to rent all their floors. this has happened in bangkok in recent years. banks wasted a lot of money on loans to build these beautiful . empty buildings.
