Today Tonight will be rolled into a one-hour news bulletin from February 10, a source has told Fairfax Media.

The Seven Network is yet to decide whether to scrap its Today Tonight brand or include it in the new program.

The source described the move as "clever" because it will lure viewers who want to watch certain Today Tonight stories but dislike "trashy" current affairs shows.

Recently, Seven extended its 6pm bulletin to one hour to cover the bushfires and floods. It has rated strongly – especially in the second half, beating A Current Affair on Nine.
