Fans of the show "NCIS: Los Angeles" can watch episodes on the CBS website or the TV website. These are offered mostly for free to viewers on both websites, though the CBS website limits the number of free episodes users can watch. The TV website's free episodes vary.
CBS offers a CBS all-access membership that will allow users to view all the episodes for the season and even allow users to view past seasons of the show. The TV website offers most of the episodes free on its primary site, though some are not available and would need to be viewed on one of the alternative options the site offers. These alternatives are not guaranteed to be free for viewers, though.
