Dear Fellow Stockholder:                                       December 7, 2005

The Special Meeting of Stockholders of Insight Communications Company, Inc.
to be held on December 16, 2005, is less than ten days away. We urge you to
participate by voting your shares today.

According to our latest records, we have not yet received your proxy for this
important meeting. Insight's board of directors unanimously recommends that
you vote FOR the adoption and approval of the merger agreement and FOR the
proposed amendment to the certificate of incorporation.

Whether you are a continuing investor or a public stockholder, your
participation is needed to help us reach the vote requirement. Your failure to

shares immediately to ensure your shares are represented at this important
meeting.

returning the enclosed duplicate proxy or voting instruction card in the
postage-paid return envelope provided.

                          IMPORTANT RECENT DEVELOPMENT

Institutional Shareholder Services (ISS), a leading independent proxy
voting advisory firm which advises institutional investors, recommended that
stockholders of Insight vote "FOR" the merger agreement and the charter
amendment.

In making its recommendation, ISS concluded that, "Based on our
review of the terms of the transaction...including the merger premium and the
increase in the offer price per Class A common share subsequent to the initial
announcement of the transaction, we believe that the merger agreement warrants
shareholder support".

ISS is a leading provider of corporate governance services.
