STER may not use more than 10% of the airtime per year on advertisement and daily more than 15% and also air ads within programs. For programming with 4 minutes commercial breaks, like Rugby World Cup events, they consider the pregame, each half of the game, halftime, and the postgame as separate programs in their programming guide and air ads between them. STER is responsible for the contents of the ads which have to be strictly separate from the programs on the public networks and not influence the programming. Complaints about ads can be made at the Advertising Code Committee (comparable to the Advertising Standards Authority in the UK). STER contributes about 200 million euro to the total budget of 900 million dollars (2013) of the El TV Kadsre.
