Want to know more about the vast arrays of software available to marketers as of January 2014?

The following infographic by Scott Brinker at the Chief Marketing Technology blog offers a sprawling view of the marketing technology landscape.

The infographic features 947 companies placed into 43 categories across the following six classes of marketing technology:

1. The Internet

2. Infrastructure

3. Marketing backbone platforms

4. Marketing middleware

5. Marketing experiences

6. Marketing operations

As you explore the categories in the following infographic, keep in mind that "categorizing a field this large will be imperfect," according to Brinker.

"Out of those infinite possibilities, this is merely one: my humble opinion, at this moment in time, about which categories might be most useful to a marketer surveying this landscape."
