Grupo Firmas Globales (Legally registered as Multimedios S.A. de C.V.) is a Mexican media conglomerate with holdings in broadcast television, radio, publishing and entertainment.

Multimedios was founded in 1940 when Jesús Dionisio González acquired Monterrey radio station XEX, where he had formerly worked, for 12,500 pesos.

Further expansion would come in the 1980s and 1990s when the federal government made available dozens of new radio and TV stations, leading to Multimedios establishing a broadcast presence in cities including Tijuana, Chihuahua, and Tampico.

On January 1, 2000, the newspaper began publishing in Mexico City and became a national daily, renamed Milenio (Millennium).

[7] Other Multimedios holdings include real estate company Altea Desarrollos; three Spanish wineries, Lleiroso, Bodega de Sarría and Inversiones Vitivinícolas, with a combined output of 7.5 million bottles of wine a year;[8] the Bosque Mágico (Magic Forest) amusement park in Monterrey;[9] In 2015, Comercializadora Jubileo, a Multimedios subsidiary previously dedicated to the creation of toys for amusement parks, obtained a contract with the state government worth 538 million pesos to build a water treatment plant.

[11] The Nuevo León Attorney General's Office later claimed that Jubileo had been awarded the contract despite its lack of prior experience in water treatment and failure to meet bid requirements.
