DTN is supported by subscriber fees and advertisers. There are over 10,000 subscribers in Minnesota. News stories are sent electronically from the Extension Service to DTN where they're sent, via satellite, directly to subscribers.
Stories are typically production-related.
To help evaluate how useful the service was to subscribers, a random sample of 125 Minnesota subscribers to DTN was drawn. Then a telephone survey was conducted from December 1995 through mid-February 1996. All 125 names were called a least twice. Of those not reached, there was either no answer or the primary DTN user was not available. There were no refusals.
