Some assume Comcast and CenturyLink are the only choices when it comes to internet service. Right now, that would be accurate but Martinsville owns its own fiber optic system called “MINet.” The service is used by the city and city affiliated businesses, and also to other businesses, but not residential. That’s about to change. A transmitter will be installed at the Martinsville High School and 10 volunteer homes within line of site will be given internet service without charge during a testing period. Service is expected to begin next month. Once the bugs are worked out, service is expected to cost $50 to $70 a month.
