The general public got to know him thanks to his television appearances, both as panel member in the quiz De Wies Andersen Show and as interviewer in the talkshow Noord-Zuid (North-South).

Due to his confrontational criticism of capitalism, the monarchy, the Church, the establishment and the far-right movement Anthierens had both a lot of admirers as well as many enemies.

In the 1970s he received his own column in Knack, where he initially was only supposed to review TV shows, but after a while he used it as an outlet for every subject in society that bothered him, always written with a healthy dose of irony and sarcasm.

In the 1960s he presented his own radioshow, Charme van het Chanson on public radio and played both French-language songs as well as Dutch and Flemish kleinkunst.

Anthierens made no secret of his hatred of the man's music and after he insinuated that the singer had not paid Peyo the rights to make a hit song about The Smurfs Abraham stood up and left the show in anger.

He was allowed back on television, however, and made a travel show about his idols Willem Elsschot and Jacques Brel, about whom he also wrote books, one published in 1992, the other in 1998.

During his later years he was best known for writing personal essays and books criticizing the Belgian monarchy, the influence of the Roman Catholic Church, commercialization and sensationalism in Flemish media and the rise of the far-right.

He also wrote a book about Irma Laplasse [nl], a Flemish collaborator during World War II ("Zonder Vlagvertoon") and the resistance leader Albert Vandamme.
