What Is the Largest Pharmaceutical Company on the Planet?

It may seem like an easy question to answer, but determining what the largest pharmaceutical company in the world is can be trickier than it looks. The definition of what a "pharmaceutical company" actually is has been changing in the past few years. Some companies, such as Pfizer (NYSE: PFE  ) and AbbVie, focus on developing and selling branded drugs, while others, such as Johnson & Johnson (NYSE: JNJ  ) and Merck, have a different strategy and are much more diversified.

So what is a pharmaceutical company, and which one is the largest in the world today? Health-care analyst Max Macaluso weighs in on this debate in the following video.

Is bigger really better?
The biggest pharmaceutical company may not be the best investment. Involved in everything from baby powder to biotech, Johnson & Johnson has its critics convinced that the company is spread way too thin. If you want to know whether J&J is nothing but a bloated corporate whale -- or a well-diversified giant that's perfect for your portfolio -- check out the Fool's new premium report outlining the Johnson & Johnson story in terms that any investor can understand.
