Actually, PEM predates PGP.  PGP was followed by MOSS (MIME Object 
Security Services RFC 1848) within the IETF and S/MIME outside the IETF 
by RSA.  Both appeared at the same time.  This was back when the RSA 
algorithm patent still applied so MOSS never had a chance.

Later S/MIME entered the IETF standards track.  Fifteen years later it 
has evolved to include the same features and functionality of MOSS, as 
well as the certificate-based solution from PEM that it always had.

PGP and S/MIME each enjoy a small amount of success but still we don't 
have a broadly deployed secure email service.  The MOSS specification 
is historic now.

If we are going to try again I would suggest focusing on the 
infrastructure, MTA-MTA communications.  I think there could be real 
value in leveraging DNSSEC for MX and DKIM protection, but that's a 
discussion for a different home.
