The final three (3) issues of print magazines under the previous Athlon Outdoors brand have all gone to print, which marks the end of the print business model. Working with the experienced quality content producers that made Athlon a household name, Bleecker Street Publications will provide the same great content the readership has come to expect in an expanding digital format.
