La Cadena SER (the SER Network) is Spain's premier radio network in terms of both seniority (it was created in 1926) and audience share (it had a regular listenership in 2009 of 4,819,000). The acronym SER stands for Sociedad Española de Radiodifusión (Spanish Broadcasting Company).

Cadena SER's programmes – which encompass news, sport, talk, entertainment and culture – can be received throughout Spain. The network's main studios are located on the Gran Vía in Madrid; in addition, studios across the country contribute local and regional news and information, with local programming in each location amounting to between two and three and a half hours daily.

Cadena SER is owned by Unión Radio, the majority shareholder in which is currently the PRISA group, a major player in the Spanish media market which also controls, for example, such music radio stations as M80 Radio and Los 40 Principales and a number of newspapers (including the influential national daily El País), as well as the digital TV station Digital+.

Fernando Alonso Díaz (born 29 July 1981) is a Spanish Formula One racing driver and a two-time World Champion, who is currently racing for Ferrari.

On 25 September 2005, he won the Formula One World Driver's Championship title at the age of 24 years and 58 days, at the time making him the youngest Formula One World Drivers' Champion. After retaining the title the following year, Alonso also became the youngest double Champion at the time. Nicknamed El Nano, a typical pseudonym for Fernando in Asturias, his place of birth, Alonso acts as a Goodwill Ambassador for UNICEF.

Fernando Alonso was born in Oviedo, Asturias in northern Spain. His mother worked in a department store and his father was employed as a mechanic in an explosives factory near Oviedo. Alonso has an older sister, Lorena. Alonso's father José Luis, an amateur kart racer, wanted to pass on his passion to his children. He built a kart, originally meant for eight-year-old Lorena, but unlike her three-year-old brother, she showed no interest in the sport.
