The head of the agency charged with ensuring smooth transition of the television industry into digital broadcasting quit the Bush administration late Friday.

John Kneuer was serving as the administrator of the National Telecommunications and Information Administration (NTIA) since May of last year.

Kneuer's resignation as president Bush's top telecommunications adviser, is set for this month and it comes amid concerns on Capitol Hill over the manner in which Bush government is handling the conversion by television broadcasters from analog to digital broadcasting.

On Feb. 18, 2009, tens of millions of televisions that are not equipped to receive digital signals will no longer be able to receive programming.

Meredith Baker, deputy assistant secretary, is set to take over Kneur's duties until the White House nominates a replacement and he will serve as acting NTIA administrator.
