Longitudes Group today announced the release of its 2015 Sporting Goods Channel Golf Market Report.  Longitudes Group estimates 17% of golf equipment/apparel revenues, in the range of $850,000,000 in retail volume, are sold in traditional Sporting Goods retailers.  Golfers and manufacturers alike have experienced the power and influence of this channel in recent years. Tides are now changing as Golf departments inside large format sporting goods stores are getting pinched as they struggle to keep up with faster growing categories across the aisle.
