The story
In June 1996, Rob Stone left a major record label to create Cornerstone, a Manhattan-based music promotion firm that worked primarily with record labels to promote their artists. After being joined by business partner and co-CEO Jon Cohen in 1997, the firm began to expand into a marketing and creative agency that integrated ip music names in corporate branding campaigns.
Stone and Cohen also founded The FADER, a music publication, in 1998.
