This week, CBS announced the renewal of a slate of shows, including rookies “Person of Interest” and “2 Broke Girls.” Other shows returning next year (most of them no-brainers) include “Survivor,” “The Good Wife,” “How I Met Your Mother,” “The Big Bang Theory,” “The Amazing Race,” “Undercover Boss,” “Hawaii Five-0,” “Criminal Minds,” “NCIS” and its offshoot, “NCIS: Los Angeles,” “Blue Bloods,” “The Mentalist,” “Mike & Molly,” and  the original “CSI.” No word yet on its spinoffs.

HBO canceled its racetrack drama “Luck” after the third horse death on set.

Playing catchup: “Terra Nova” fans probably already know the Fox show was canceled. If you don’t, sorry to break it to you.

This week, TNT and NBC announced shows coming this summer. For TNT, “The Closer” airs its final six episodes starting July 9, with spinoff “Major Crimes” debuting after “The Closer” finale on Aug. 13. Other shows returning on TNT this summer include “Rizzoli & Isles” and “Franklin & Bash” (June 5); a new “Dallas” (June 13); “Falling Skies” (June 17); reality competition “The Great Escape” (June 24); new series “Perception” (July 9); and “Leverage” (July 15).

For summer, NBC is bringing back “Love in the Wild” and debuting medical drama “Saving Hope” (June 7). (Because we don’t have enough of those.)

A side note: CW changed its policy on streaming, making episodes of its shows available a day after airing instead of three days.
