(NASA immediately launched NASA TV as the ACSN's internal replacement.) The channel mostly featured documentary content pertaining to nature, science, history, current events, medicine, technology, cooking, home improvement, and other information-based topics. These are often agreed to have been more focused, more technical, and of a more academic nature than the content that was being broadcast at the time on its rival, The Discovery Channel. The channel was geared toward an inquisitive and narrow audience during this time, and had modest ratings except for Captain's Log with Captain Mark Gray, a boating safety series which aired on TLC from 1987 to 1990 and achieved between a 4.5 to 6 share in the ratings. Captain's Log was also the highest compensated series in the history of TLC, with over 30 times the compensation of any other series on TLC at that time and was allowed to sign yearly rather than quarterly contracts.
