El Trece
Since 1994, the chain has carried out, together with UNICEF, the program un sol para los chicos (A sun for chidrens), dedicated exclusively to the donation of money for this institution, by companies and viewers.  The latter are encouraged through telephone games with famous people and raffles.  The program has several hosts throughout the transmission and most of the network's figures also participate;  it is issued every year, on Children's Day, generally lasting 9 hours.  During the program, concerts are held for the same purpose of raising funds.
