He also is responsible for shepherding Cox's transition to digital for both television and radio stations.

Another leadership role for Davis has been in the advancement of broadcast engineering standards and technologies vital to the evolution of the broadcasting industry.

For three years, he chaired the ATSC Planning Committee, studying the next stages in the evolution of DTV.
