(CNN) -- Henry Olszewski was stoked in 2008 when he, along with millions of Americans, drafted New England Patriots quarterback Tom Brady to his fantasy football team.



Tom Brady's season-ending knee injury last year sparked an idea at Intermarket Insurance.



About eight minutes into the season, a 220-pound safety was blocked into Brady's knee, tearing two of the quarterback's ligaments. Brady's season ended, as did Olszewski's.



"That Monday, [Olszewski] came in the office, and he was bummed out," said Anthony Giaccone, president of Intermarket Insurance. "He asked, 'Why can't we buy insurance for fantasy team players?' "



Thus spawned the brainchild for Fantasy Sports Insurance, which guarantees that NFL players won't miss a certain number of games. FSI will reimburse a fantasy player's entry fee if they do.



It's one of a blitz of bizarre businesses cropping up in the $800 million industry of turning quarterback stats to greenbacks, said Paul Charchian, president of the Fantasy Sports Trade Association.  See fantasy football's top 10 prospects »



Charchian is familiar with the wellspring of offbeat companies fueled by the fantasy football craze; he owns LeagueSafe, which stores league entry fees in a bank until it issues a payout to the winner at season's end.



Other specialty businesses, he said, range from the obvious, such as trophy companies, to the esoteric, such as fantasy dispute resolution.

For the uninitiated: Fantasy football players generally "draft" NFL quarterbacks, running backs, wide receivers, tight ends and team defenses and use their statistics each week to score points in head-to-head matchups.

The NFL has introduced the RedZone Channel, which flips between games where a team is on the verge of scoring, CBSsports.com has launched a live Web show called "Fantasy Football Today," and cable's FX is scheduled to air a sitcom based on a fantasy football league this year.



The stakes have skyrocketed as well. The World Championship of Football offers a $300,000 top prize. The Fantasy Football Open Championship's is $1 million. The Wall Street Journal reported last year that a group of well-heeled financiers has a 10-team league with a $100,000 entry fee.



A June study by the research company Ipsos says three in 20 American men (and one in 20 women) play some fantasy sport.



"It takes the fans of one sports team and makes them interested in every game that's happening," said Jason Kint, senior vice president and general manager for CBSsports.com. "It's a welcome escape, as much of sports is right now."



Not all fans are enamored, however. ESPN's Colin Cowherd explained his aversion on his radio show last month, saying fantasy football was too time-consuming and, in his experience, for "total nerds and geeks."



"I'm a gambler, lived in Vegas. My friends are gamblers. We don't play fantasy football," he said. "We're busy. We have jobs. We have careers. We have lives. We don't have time for three-hour draft parties and an hour or two on the computer every week to update our fullback situation."



But more than 22 million Americans and Canadians do, Charchian said, and the economic downturn doesn't seem to be sacking the industry.



"It's hard to get out. It's enmeshed in your social circle," he explained.
