With a licentiate in Journalism from the Autonomous University of Barcelona, Inés Ballester started her career at Cadena SER, and later went on to the daily magazine of Radio Nacional de España.

After a few years she made the leap to television, first at the territorial center of Televisión Española (TVE) in Valencia, as head of programs, and then on Nou and Telemadrid.

Shortly afterward, Ballester joined another morning show at La 1, in this case on weekends, under the title El día por delante [es], which premiered on 24 May 2008.

In the summer of 2012, she was diagnosed with breast cancer, for which she received surgical treatment at the Jiménez Díaz Foundation University Hospital [es].

The 18 February 2015 edition of this program generated controversy by giving publicity to a false photo of the Podemos candidate for the Presidency of the Government of Andalusia together with a nude woman.
