TSC began as a publisher. Our flagship title, Ocean News & Technology (ON&T), has been in continuous publication for more than 46 years—making it one of the longest-running and most recognized trade magazines in the ocean technology sector. What started as a single editorial voice grew into a portfolio of four distinct media brands, each serving a defined audience within the broader ocean and offshore industries.

The expansion into marketing services was not a pivot. It was a natural extension. After decades of producing content for this industry—covering its technologies, tracking its companies, attending its conferences—TSC had built something most marketing firms spend years trying to acquire: genuine domain expertise and trusted industry relationships.
