There was encouraging news all around for the production industry in July. The Creativity Production Index - the average number of commercials produced by a sample of agency offices - held relatively steady and bested last July by more than an index point. Through the first seven months of the year, the Index continues to outpace the same period in 2002. Meanwhile, Los Angeles appears to have emerged from its slump. After posting the lowest production figures since the 2000 SAG strike in May and June, the Los Angeles Film office recorded 421 production days in July, a 3.7 percent increase over last year. But L.A. still has some ground to make up. Through July, production days there lag behind 2002 totals by 3 percent.
