Mario Pergolini

In 1994 he created, together with partner Diego Guebel, Caito Lorenzo and Sebastian Melendez the Cuatro Cabezas (or 4K) TV production company, which is now one of the three most important media holdings in Argentina.

The CQC format has been sold to several countries (Chile, Brazil, Mexico, France, Italy, Spain, and Israel).

The Israel TV version (anchored by Avri Gilad) did not catch with Israeli audiences and was discontinued after half a season.

His last episode did not include any special retrospective, but Pergolini criticized Telefe's management on the air (arguing that they cannot threaten him now) and joked with his colleagues Eduardo de la Puente (also retiring) and Juan Di Natale, who was still hosting CQC in 2009.
