Concluding that the show has run its course, CNBC has canceled “The Real Story.”An estimated 10 staffers associated with the show may lose their jobs when the last episode of the Boyd Matson/Cassandra Clayton-hosted program airs on Jan. 22, a CNBC spokesman acknowledged. But he said the cable network may try to place them in other jobs at CNBC, perhaps with the upcoming “Tom Snyder.” In January, broadcasting veteran Tom Snyder is returning to TV with a Monday-through-Friday, hourlong, prime time talk/call-in show that will be CNBC’s first series emanating from Los Angeles (Daily Variety, Oct. 26). “Real Story” has gone through numerous changes since its debut in early 1991. It began as a 90-minute magazine show touted as a prime time version of “Today”; three months later, CNBC expanded it to two hours. But several months later, it was cut to one hour, with the cable web introducing a half-hour spin-off emphasizing softer news, “Real Life.” In September, CNBC cut “Real Story” to 30 minutes. Asked to comment on the reasons behind the cancellation, the spokesman said its two-year run as a reasonable length of time for a show that “has not shown break-out potential.” Its ratings have consistently been in the low to middle of CNBC’s prime time fare. In January, CNBC will re-jigger some of its primetime schedule. Among the changes: The current half-hour “Pozner and Donahue” will expand to an hour on Tuesday and Thursday at 9 p.m. (EST); the half-hour “McLaughlin” will also expand to one hour, airing Monday and Wednesday at 9 p.m. On Friday, CNBC will air back-to-back half hour “The Dick Cavett Show” at 9 p.m. “Talk Live,” which currently airs at 10:30 p.m. on Saturday, will switch to 9 p.m. on that night.
