                                                                    Exhibit 99.1

  InterDigital's Board of Directors Increases Share Repurchase Program to $350
                                    Million

    KING OF PRUSSIA, Pa.--(BUSINESS WIRE)--Dec. 28, 2006--InterDigital
Communications Corporation (NASDAQ: IDCC) announced today that its
Board of Directors has approved the expansion of its current share
repurchase program from $200 million to $350 million. The Board based
the higher authorization amount upon strong positive cash flow
generated in 2006 as well as anticipated high levels of free cash flow
in 2007. Under the current $200 million repurchase program, the
company has repurchased 6.4 million shares for $187 million as of
December 27, 2006.

    "Our business continues to generate substantial free cash flow.
Indeed, in first quarter 2007, in addition to expected payments
related to current royalties, we anticipate receipt of either
scheduled license fee payments or new pre-payments totaling
approximately $120 million from existing patent licensees," commented
William J. Merritt, InterDigital's President and Chief Executive
Officer. "These high levels of free cash flow allow us to build
shareholder value in three ways: the advancement of our internal modem
product development in support of product launch targeted for the fall
of 2007, acquisitions of technology, and significant share
repurchases."

    "Since 2003, InterDigital has invested substantial amounts in
research and product development, funded complementary acquisitions of
patents and technologies and expended nearly $300 million repurchasing
approximately 11 million shares, or approximately 18% of diluted
shares. Our high level of share repurchases in recent years together
with this expansion of our current program reflects both our
confidence in our ability and our commitment to enhance shareholder
value," said Richard Fagan, InterDigital's Chief Financial Officer.
"In addition, we plan to initiate steps in 2007 to help reduce our
weighted average cost of capital and further enhance shareholder value
by introducing prudent levels of debt to our capital structure."

    Pursuant to the repurchase program, shares may be purchased from
time-to-time, through open market purchases, pre-arranged trading
plans or privately negotiated transactions. The amount and timing of
purchases will be based on a variety of factors, including potential
share repurchase price, cash requirements, acquisition opportunities,
strategic investments and other market and economic factors.
