Some sort of syndicated "alternative" program? It was apparently headquartered in the Twin Cities area.
I found this on some St. Paul cultural interview schedule from 2016:
"Ramsey County Historical Society
Television: Medium to the Mind — Preserving the Interviews of TELLSTAR NEWS
TELLSTAR NEWS, a nationally syndicated news and commentary television program, brought viewers alternative perspectives and information on critical issues facing the nation and the world; 112 half-hour interviews have been saved from its six years of production. Ramsey County Historical Society would like to conserve, preserve, and share these important stories with youth and adults within the Cultural District and Saint Paul Public Schools. Funding in the amount of $12,430 from the Cultural STAR program will enable the conversion of all interview videos into a digital format, produce four 10-minute videos for classroom use, and make all of these resources available to the public on the RCHS website."
The video description says 1986-1995.
