Filming of commercials on location in Los Angeles has been steadily growing in recent weeks, good news for an industry in which advertisers have been drastically cutting back television ad spending. The Los Angeles Times reported today (Wednesday) that commercial filming generated 102 production days on Los Angeles streets last week, twice last year's numbers during a comparable period. Despite the recent upturn, however, on-location filming of commercials is down 21 percent for the year versus 2008.
