Broadway's best have been recognized every year in this awards event since April 4, 1947. First televised broadcast was in 1967. The Tony Awards typically features musical numbers from nominated musicals. Over the years, they have occasionally featured excerpts (live and/or filmed) from nominated plays, as well. Over the years, the telecast has been hosted by the likes of Angela Lansbury, Hugh Jackson and Rosie O'Donnell, who, at the height of her popularity, boosted the ratings considerably. Networks airing the program have varied and sometimes technical awards have been presented on a second PBS broadcast directly preceeding the main event. While honoring the best of Broadway, it is the single biggest promotional event for New York Theatre each year.
