Philadelphia Inquirer: Comcast, as part of a business diversification at its 24-hour Golf Channel network, is attempting to do for golf what Expedia, Orbitz and Priceline did for travel: take the reservations systems online, so that golfers can comparison shop. GolfNow (www.golfnow.com) expects to book 15 million rounds at 9,000 courses this year, and it expects big growth in coming years as younger generations of golfers conversant with technology and mobile apps flood the links, putters and drivers clanging in their golf bags.
