12. Segment Reporting

We view our operations and manage our business as one segment: the development, marketing and licensing of technologies and fonts. Factors used to identify our single segment include the financial information available for evaluation by our chief operating decision maker in making decisions about how to allocate resources and assess performance. While our technologies and services are sold into two principal markets, Creative Professional and OEM, expenses and assets are not allocated to these market segments, and operating results are assessed on an aggregate basis to make decisions about the allocation of resources. The following table presents revenue for these two principle markets (in thousands):


	Three Months Ended June 30,				Six Months Ended June 30,
	2018		2017		2018		2017
Creative Professional	$	38,417	$	30,642	$	73,415	$	57,713

Total	$	60,687	$	57,801	$	117,370	$	110,266

Geographic segment information

We market our products and services principally through offices in the United States, United Kingdom, Germany, China, Republic of Korea and Japan. We report revenue based on the geographic location of our customers. For example, licenses may be sold to large international companies, which may be headquartered in the Republic of Korea, such revenues would be included in the revenue for Rest of World.
