Some interesting statistics about the adult film industry here. I’d be curious to know what the 90% confidence intervals are around these estimates, because many of them seem surprising. For instance, the claim that the San Fernando Valley produces 90% of all adult films and releases 20,000 adult movies a year seems unrealistically large. It is also claimed that the total worldwide revenues to the industry are $97 billion. So if 90% of that flows to California, where the San Fernando Valley is located, then it contributes $87.3 billion to California’s GDP. This would be 4.7% of California’s $1.8 trillion GDP, which would be twice the direction contribution to the economy of agriculture, and 65% as large as total exports. Does that sound believable? Are there better numbers on this?

Even believing the numbers, your calculation seems off base. Even if 90% of films are made in SFV, it does not mean 90% of ‘worldwide revenues’ flows there. The actual production is just a (small) part of adult film trade. Marketing and distribution are two obvious activities which contributes a lot to the gross worldwide number. Both are unrelated (geographically) to the production.

Might well that the “revenue” just doesn’t show up when it comes time to taxed, similar to the huge drug trade that contributes to the underground economy.

I agree with Tom. These numbers could be possible given how large the underground economy is purported to be.
See TED talks about it here:

Morten, divide the number in half then- it is just as remarkable.

I’d agree that the figures seem a little off in some respects – for example 20,000 films and $97 billion implies that the average film makes revenue of $5 million – highly unlikely. Especially when a production spend of $100,000 per film is unusually high – as this interview with Bill Asher implies.
The interview (linked from one of the sources on the graphic) is quite revealing: http://www.pbs.org/wgbh/pages/frontline/shows/porn/interviews/asher.html
Asher is head of Vivid. In 2001, he estimated an industry size of between $4 and $10 billion, but this was not all in films. The pie chart on the linked graphic indicates that about two-thirds of adult revenues are in China, Japan and Korea and I would imagine that they are not buying primarily American movies. But perhaps someone with more experience can correct me.
Asher does say something revealing: the cable TV networks take 80% of revenue on adult pay-per-view films. Similarly, adult websites probably make much more ad revenue than they pay out to the filmmakers. So your 50% estimate is probably too high. On Asher’s figures, a more accurate number would be (say) $7 billion revenues of which no more than $1 billion is likely to be going to SFV film companies.
Ultimately, the thing to remember is: the 90% confidence intervals are huge, for the simple reason that these are not economic statistics – they are business-magazine statistics.
You can see a huge list of inconsistent stats at the following link (which is from an anti-porn pressure group, and appears to have been cherry-picked to make the graphic that you link to):

And on the subject of whether they’re paying taxes:
“It employs in excess of 12,000 people in California. And in California alone, we pay over $36 million in taxes every year. So it’s a very sizeable industry,” says Bill Lyon (from http://www.cbsnews.com/stories/2003/11/21/60minutes/main585049.shtml).
That’s a whopping $3,000 per person. Not entirely sure they’re paying everything they should, then.

Interesting points Leigh, I think your $7 billion estimate sounds fairly reasonable. Interestingly, the Vivid guys claim that they only filmed 80 movies a year, which puts the 20,000 movies out of California into question even more.
I do think Cable networks probably have significantly more market power than internet sites, since the barriers to entry are much lower. So I wouldn’t guess that websites would be able to bargain for a big piece of the pie like networks can.
The Vivid interview and CBS story are both very out of date, I imagine that the increase in broadband internet has dramatically changed the nature of the industry over the last 5-10 years. I’d be curious to read more up to date information.
