History In 2000, Acesa Telecom (later Abertis Telecom) acquired 52% of Tradia and merged into Abertis Telecom (now Cellnex Telecom). Three years later, after Auna was spun-off, Retevisión's audiovisual business became part of Abertis Telecom. In 2005, the deployment of Digital Terrestrial Television began in Spain, with a network that reached 80% population coverage carrying out the first tests in Madrid, Barcelona, Valencia, Zaragoza and Gijón. In 2006, the company was awarded the contract by which it became the operator of DTT signals for Spanish broadcasters with national coverage.
