Teilifis na Gaeilge signed what it described as the biggest single contract yet for the independent television sector at a ceremony in Spiddal, Co Galway, yesterday. The contract, worth over Pounds 2 million a year for three years, is for Ros na Ru, a soap opera which will be broadcast four nights a week on the new station with an omnibus edition at the weekend. It will be produced by Tyrone Productions and Eo Teilifis as a joint venture.
