The document discusses three business failures - Sony Satellites, Unicom, and Coal. Sony Satellites was a dish retailer started in 1997 with 100,000 start-up capital that failed due to lack of order fulfillment, technology, capital, and management skills. Unicom was a cable network business that failed due to lack of marketing skills, management, and fee collection issues when faced with a competitor undercutting prices. Coal was a partnership transporting coal for brick makers but failed due to high costs, untrustworthy partners, and competition.
