2.       We note your response to prior comment three. Please address the
following items related
         to your advertising services arrangements:
           Please further discuss how you determined that your creative
services and production
             services should not be combined into a single performance
obligation. In this regard,
             we note that you have a significant level of oversight associated
with the production
             services and that the production services use the creative
services you have provided.
           Please provide us with a more specific and comprehensive discussion
of how you
             considered the definition of control in your analysis and whether
you are directing the
             use of production services.
           Tell us when you recognize revenue related to production services.

         In order for us to better understand your analysis, please provide us
with representative
         contracts and related invoices, if applicable, for these arrangements.
3.       We note your response to prior comment three. Please address the
following items related
         to your media services arrangements:
           Please further discuss how you determined that your media planning
and media buying
             should not be combined into a single performance obligation. In
this regard, we note
             that the media spots purchased are in accordance with a buying
guideline that you
             have developed.
           Please provide us with a more specific and comprehensive discussion
of how you
             considered the definition of control in your analysis and whether
you are directing the
             media buying services.
           We note your statement that you neither purchase nor commit to
purchase media spots
             before they are sold to clients. Please help us better understand
when media spots are
             purchased and how purchases might differ by medium. Please
specifically address
             spots purchased through the upfront advertising market for the
television broadcast
             season.
           Please further describe your consideration of pricing discretion. We
note your
             disclosure on page 9 that you may earn commissions when clients
pay you the gross
             rate billed by media and you pay for media at a lower net rate.
           Tell us when you recognize revenue related to purchased media spots.

         In order for us to better understand your analysis, please provide us
with representative
         contracts and related invoices, if applicable, for these arrangements.
        You may contact Kathryn Jacobson, Senior Staff Accountant at (202)
551-3365 or Robert
Littlepage, Accuntant Branch Chief at (202) 551-3361 if you have questions
regarding comments
on the financial statements and related matters.
