Planeta is the primary shareholder of the media group Atresmedia (dominating alongside Mediaset España the free-to-air television landscape in Spain under a duopoly) and the publisher of the Conservative newspaper La Razón.

[5] In 1992, Planeta acquired the Espasa Calpe publishing company and the Casa del Libro [es] bookstore chain.

[10] After the merger, LaSexta somewhat retained a perception of a left-leaning profile, starkly contrasting to those of the rest of Planeta media properties.

[citation needed] With its purchase of Editis in 2009, Planeta became one of the largest publishers in the world,[11] with over 1 billion dollars of revenue that year.

[13] Hitherto headquartered in Barcelona,[14] Grupo Planeta decided to move its head office to Madrid in October 2017 because of the "uncertainty" caused by the thwarted Catalan declaration of independence.
