The way that the Shaw Direct people wrote it for their onscreen guide, they are referring to the tinned meat product. The differences are very clearly explained mere minutes into the documentary. Should be Spam, not SPAM.
In related news, I looked it up at imdb.com and found this review there:
First of all, it was not pour, nor was it poor! It was very good! Throughly researched and informative. How many experts from around the world does the guy have to talk to before this dumb reviewer sees how much went into it? :/
And finally, on the subject of SPAM, I made this little edit for a guy who calls himself Spamtron. He makes chiptunes.
Simple but effective, no? :)
