Assuming it's a public blog and not an internal company blog anyone will be able to view the blog.
Blogs were originally called "weblogs," a term coined by Jorn Barger in 1997. The name combined "web" and "log," reflecting the format of online journals or logs where individuals could share their thoughts and experiences. Over time, the term was shortened to "blog," which gained popularity as the medium evolved.
Unfortunately this is currently unavailable as a public document. I can tell you that there are over 10,000 blogs created on blogger alone.
Corporate blogging can be viewed on external public blogs. Corporate blogs are written primarily for consumers or for other businesses. One of the most popular corporate blogs is the official Google Blog.

Some disadvantages of web logs, or blogs, include the potential for lack of credibility and reliability as anyone can create and publish a blog without rigorous fact-checking. Additionally, blogs can sometimes lack privacy as they are often public and can be accessed by anyone. Lastly, maintaining a successful and popular blog requires consistent time and effort, which may be a challenge for some individuals.
Most blogs are available to use (write) from the age of 13 an up. Anyone at any age can read the blogs that are posted on the internet.

If by "blogs" you mean from Blogger.com, then no, they are all open to the public. However, you may change the options for that while either creating a blog (it asks you while you make it), or simply click "customize".
