From Traverse Legal:
Parking companies are handcuffed in many ways by their relationship
with Google and Yahoo, who essentially control the framework by which
ads are shown on parking pages. Parking companies, however, now appear
to realize the necessity of working with Google and Yahoo to develop
options which allow a domain owner to exclude categories of ads which
are shown on parked pages. Based on several conversations with parking
companies at the recent T.R.A.F.F.I.C show that keyword category and
trademark exclusion will soon be available.
