They have bought media companies all around the country. They bought tv stations in every major city and shut down local programming. They produce everything in Buenos Aires and it's seen in the whole country. It won't boe a problem if there were local alternatives, but since Clarin bought them... The same goes with newspapers and radio station.
Now, they owned a cable company named Multicanal. The only competence was Cablevision, but they have divided coverage areas so they don't overlap, so there was no real competence. They provided cablemodem service over Multicanal, but it was really shitty and nobody used it. What they did is buy stakes from foreign holders of Cablevision so they could control both cable companies, and now they have done a customer reacomodation, meaning that you had multicanal and now you have cablevision and multicanal has no customers. Fibertel (The ISP) was a company owned by the same owners of Cablevision. Fibertel was licensed to provide cablemodem, but Cablevision was denied, so the trick was Fibertel owning the cable wires and providing internet access, and Cablevision "renting" fibertel's network and providing cable signal. If you had the two services, you had to pay two bills separately. On Jan 15 Grupo Clarin made Cablevision absorb Fibertel, dissolving Fibertel's legal personality, but intended to use the license granted to Fibertel. In Argentine law, in a regulated communications market, these licences are not transferibles, so that was not approved by the government and were told to stop subscribing new customers. They didn't stop, and tryed to keep operating illegaly.
