Although Coco-cola and and Pepsi have no loyal customers, but they both still in the top 20 brands in all around the worlds.. the question is HOW?

Although Coca-Cola and Pepsi and have no customer loyalty, but both are still in the top brand all over the world .. The answer is simply because it is one of the oldest leading companies in this field and is characterized by that has branches in all countries, capitals and all the provinces and the fleet of transportIt is able to distribute its products all over the world

This is not the question of HOW they are world`s leading brand...........but the Bigger question is HOW DID THEY DO THIS? 

The Coca Cola Beverages and Pepsi together occupy more ten75% of the carbonated soft drink market across the globe. Both of these companies have made great investments over the years, both offer solid growing dividend yields, and both excel in a particular niche. However, going forward, I think one of these companies has the edge on the other as an investment. On the other hand, Pepsi's snack division makes up about50% of the company's sales volume. Soda is just25% of the company's U.S. sales compared to60% of Coca Cola's. What this all means for investors is that Pepsi is better prepared to handle the unstoppable trend away from its flagship product than Coca-Cola. Hence, I conclude that the smart investments along with continuous R&D have been the reasons for these two brands to be among the top in the world.

I'm afraid your premise is incorrect. Both have large numbers of loyal customers, particularly in the USA.   If you're old enough, do you remember the outcry when Coke changed their recipe to "new coke"?   Coke were forced to backtrack by their loyal customers. 

Pepsi and Coca Cola are the oldest soda companies however that isn't the reason.These companies spend a lot on their Marketing and Sales Stategies and channels. Also they keep renovating their looks and extend their advertising so they have more exposure. They do many sponsorship and offer rewards.

That Ybebsy and Coca-Cola Company of the oldest companies in the field of beverage homeland and the Arab world and was in ancient times there are no competing companies and these companies have the marketing expertise and fleet of large sell me ensure their proliferation and promote their products and speed meet the needs of consumers and those companies a great ability to compete and spread unlike many companies do not have these features and despite what is written against those companies they strive to provide their products different and sophisticated sizes and thus forcing the consumer to buy their products for non-alternative presence in some areas, other than that it offers its own propaganda on all means of publishing, radio and television and provides for sellers refrigerators display to showcase their products at no charge so the financial position of the company and the management style and Advertising successful and this is evidence of the success of the administration in achieving the goals set by the company and you our sincere thanks and appreciation.
