Spinning out an information company — the seed of STNet (1984)
Waiting for the rules to open: a use of time
What draws attention in this decision is not the speed of entry but the interval. The company separated out in 1984 was not a telecom carrier at all; it merely handled information processing for the group. The Type I telecommunications licence came five years later, once the regulatory framework was in place and an internal structure for selling circuits existed. Building the vessel first and pouring the business in afterwards is how a foothold for earning outside the electricity business was quietly prepared.
A second reason the business held up is that it never left the region. Most of the new entrants that competed on national long-distance networks were swept into consolidation; STNet instead bundled corporate lines, internet and cable television within the same footprint as the utility’s supply area, and held the position of the region’s communications infrastructure. Even after the 2010s, when liberalization sent the parent’s own customers to new retailers, this business kept growing its profit. It reads as a case of a company that lost its territorial monopoly putting roots back into the same territory in a different form.
