Why there might not be another TV blockbuster like ‘Game of Thrones’

New York CNN Business — The final season of “Game of Thrones” isn’t airing until 2019, but the race is already underway to find the next king of television. Streaming services, such as Netflix and Amazon, and more traditional networks like CBS, are spending millions of dollars to find the next series that will fill the giant hole “Game of Thrones” will leave behind. When “Game of Thrones” premiered on HBO in 2011, it had far less competition — streaming services weren’t as popular as they are today. Viewers can now pick from hundreds of programs on cable and streaming services, so “Game of Thrones’” success is worth all the gold in Casterly Rock.
