Cassette tapes are big business in prison

Over at BB Gadgets, John Brownlee riffs on an article about Pack Central, a company that sells popular recordings on cassette. The target market is prison inmates. From BB Gadgets:
...Who is buying (owner Bob) Paris' cassettes? America's 2.3 million prisoners. Which brings us to the second advantage of tape over compact disc: a tape can't be broken apart and used as a shiv. Prisoners are allowed to have them. 60% of Paris' business is in cassette tapes.

Paris' excited conclusion: "[By selling cassette tapes] I have dodged every conventional bullet that has hit most music retailers," Paris says. "I don't have to worry about downloading, legal or illegally. The beauty of it is that prisoners don't have Internet access and never will."
