He has been writing about film for over forty years and in the 1970s he began co-hosting a weekly movie review television show, Siskel & Ebert, with Gene Siskel of the Chicago Tribune. When Siskel died in 1999, Ebert auditioned several co-hosts on a non-permanent basis (commonly one show). In September, Chicago Sun-Times columnist Richard Roeper became the permanent co-host and the show was renamed Ebert & Roeper.
Every year Ebert publishes a book of movie reviews from that year; he has also published a book of movie clichés and a book of essays about great films, as well as a book of essays about films he hated. Ebert also hosts Roger Ebert's Overlooked Film Festival every year in Champaign, Illinois.
An outspoken opponent of the Motion Picture Association of America, Ebert often strongly condemns the organization in his columns for their regulations regarding which movies are "suitable for children."
