The first three are ok. As for Google and Microsoft, if people don't announce some upcoming products in advance, who really knows how they operate and what they are developing at present? If you draw a serious conclusion, hearsay and speculation are inevitable and will not be objective and comprehensive.
However, the popularity and influence of these enterprises can still be compared.
Tencent and Alibaba are very influential in China. In other words, China people don't know that Tencent and Alibaba are "rare", but they are little known internationally, but their popularity among overseas Chinese is relatively high.
So Tencent and Alibaba have a great influence on China people.
Amazon is a multinational e-commerce enterprise in the United States and the largest Internet retailer in the world. Nothing can't be bought except airplanes and cannons. The reason why it can sit on the position of the world's largest online retailer is because of its high integrity.
It's hard to say whether you will occasionally buy inferior products, but brands are rarely fake.
So Amazon's retail industry has a considerable influence on customers all over the world.
Google and Microsoft are somewhat similar, both IT giants, but the international praise for Google is far greater than that of Microsoft.
If Google shares 1 120 and Microsoft shares $36, consumers will obviously have more confidence in Google.
Microsoft's products are available in China, while Google's products are rare in China, namely Google Maps (which can only use some functions) and Google's Android system.
Books, movies and reviews under googlePlay; Google+； google drive？ youtube？ Map related products; ? Statistical tools; ? Mobile standalone applications; ? Field trips ... and so on, which is unknown in China, so it is difficult to explain and compare here.
