Although critics liked it, The Addams Family series was not particularly successful, having been abandoned by ABC after only two seasons. It nonetheless left a strong impression, far greater than expected for a black and white sitcom with anemic ratings (62nd in its second season). It is clearly remembered by all my boomer friends, and I can recall that it had cultural resonance at the time. It made the cover of TV Guide more than once, and there was a short period back in the day when my asshole high school buddies and I would always substitute “Why, thank you, Thing” for a simple “thanks.”
It endures in syndication, and has been lovingly rebooted again and again. As a commenter notes, both seasons are available on archive.org for those interested. Thank you to commenter (and of course, to Thing.)
After “The Addams Family” finished its two-season run, Loring joined Phyllis Diller’s sitcom “The Pruitts of Southampton.” The critics were somewhat less enthusiastic about that series. In 2002, TV Guide ranked The Pruitts of Southampton the 20th worst show of all time. (Full list.)

Way back in 2007, Brainscan did a collage from this poor-quality VHS.
Those actually look like they would be damned sexy scenes if we had them in high definition.
