Newsweek was a magazine seen in the Dixon Hill holoprogram The Big Good-Bye. It was published in the United States of America in the mid-20th century. Mack, the news vendor, sold copies of Newsweek.
When Captain Jean-Luc Picard, Lieutenant Commander Data, and the historian Whalen ran the program in 2364, the vendor had an edition from 1941 on sale. (TNG: "The Big Goodbye")
