When it comes to the field of marketing technology, the landscape is changing rapidly. No, seriously — the picture you see below is a layout of all the companies involved in a variety of fields, counting into the hundreds, and even thousands.

The report, compiled by Mediapost, shows just how much the landscape is changing, and it’s getting to the point that even the experts in the field can’t keep up with all the companies that have popped up over the last few months.

Compiled by Scott Brinker, co-founder for ion, the chart shows a listing of 1,876 companies and open-sourced projects, spread across 43 different categories. These calculate to twice the numbers from the previous report posted in 2014, with 947 different companies split into the categories.

With the report, Brinker points out that broader marketing technology has become king, even overcoming some of the better-known companies in the ad tech industry.

Growth of these companies should continue onward, and the IDC is reporting that companies worldwide will spend a massive $22.6 billion on marketing software for the new year. It’s estimated to grow even further to $32.3 billion by 2018.

There aren’t many changes to the categories with this year’s report, although there are some inclusions like performance and attribution added to it. “I broke out from the social media category a separate category for influencer marketing,” explained Brinker. “We’re now seeing a set of companies specializing in managing relationship with influencers.”

With the overflowing chart above, Brinker believes that, while there will be growth with scale and scope of companies, there also needs to be management involved to keep things in balance.

Technology will continue to play a key part with these companies as well, with marketing tech picking up through the introduction of new products in the Internet of Things field, as well as new digital physical experiences (3D printers and other objects of the like) that will keep consumers interested in these companies.
