There are a few reasons why Amazon doesn't produce as many original series as Netflix.
First, Amazon's focus is primarily on e-commerce, not entertainment. While Amazon does have a streaming service, it's not the main focus of the company.
Second, Amazon's budget for original content is much smaller than Netflix's. Netflix spends billions of dollars on original content, while Amazon only spends a few hundred million.
Third, Amazon doesn't have as much experience in producing original content as Netflix does. Netflix has been producing original content for over a decade, while Amazon only started producing originals in 2013.
Fourth, Amazon's originals tend to be less popular than Netflix's. Although there are some hits, like The Marvelous Mrs. Maisel, most of Amazon's originals don't get the same level of buzz or acclaim as Netflix's.
So, the reasons why Amazon doesn't produce as many original series as Netflix are that Amazon's focus is on e-commerce, Amazon has a smaller budget for original content, Amazon doesn't have as much experience in producing original content, and Amazon's originals tend to be less popular than Netflix's.
