Grissom rules in Spain, and the green ogre commands a large following, too.

According to a report by research org Multimedia Corp., DreamWorks Animation’s half-hour special “Shrek the Halls” was the top-rated show in Spain last year.

Its Christmas Day transmission grabbed a 37.3 share, or 6.9 million viewers, to place it at No. 11 in the top 50 programs.

“CSI” and “CSI: Miami” were the highest-rated skeins, placing a combined 17 segs in the top 50.

Top among these was an episode of “CSI” that was No. 14 with a 30.7 share and 6.2 million viewers. The show nabbed another eight slots, while “CSI: Miami” filled eight.

In 2006, “CSI” in all its iterations accounted for eight segs in the top 50.

Spain’s top-rated domestic series last year was “Aida,” with six slots in the top 50.

Sports programming filled the top 10.

The report underscores the value of international — mostly Hollywood — series for some terrestrial broadcasters in Spain.

Foreign series accounted for 20.6% of airtime at Cuatro, compared with 28% of the net’s 7.4 audience share in 2006.

Spain bucked the trend in European viewing habits, posting a spectacular rise in the average time Spaniards spent watching TV, up from 3 hours, 37 minutes, in 2006 to 3 hours, 43 minutes, last year.

Average smallscreen viewing remained broadly flat in France last year — up just three minutes to 3 hours, 27 minutes, according to Mediametrie. It dropped four minutes in Germany to 3 hours, 28 minutes, and was 10 minutes down at 3 hours, 6 minutes, in the Netherlands.

“Increased TV consumership was especially notable over summer and in low-income groups — up 20 minutes last year. That can be put down to the influx of immigrants and the onset of an economic slowdown,” said Multimedia Corp. prexy Eduardo Garcia Matilla.

For the fourth year running, Telecinco topped broadcaster ratings in Spain, with a 20.3 all-day share, down from a 21.3 in 2006. Antena 3 TV slid from 19.5 to 17.4, and TVE-1 from 18.3 to 17.2.

The broadcast network market fragmentation can be ascribed first and foremost to the growth of two newish analog broadcasters in Spain, Cuatro (up from 6.4% to 7.7% in 2007) and La Sexta (up to 4% from 1.8%), plus the creep of a multichannel TV universe in both pay TV and free digital terrestrial television.

DTT achieved a 23.4% household penetration and a fourth quarter 9.5% audience share.

Digital feeds of webs’ core analog channels — Telecinco, Antena 3 and TVE-1 — still dominate DTT viewership.

But Spaniards are warming to DTT channels offerings kids and sports programming, led by A3TV children’s service Antena Neox, which nearly doubled its thematic channel aud share from 0.9 in 2006 to 2.0 last year.
