while the new channel will soon be available in 40 million households, Al Jazeera faced a setback when Time Warner Cable -- which reaches 12 million homes -- announced it was dropping the low-rated Current, which occupied a spot that could have been switched to Al Jazeera America.

Joel Hyatt, who co-founded Current TV with former Vice President Al Gore, told staff in a Wednesday night memo that Time Warner Cable "did not consent to the sale to Al Jazeera."

"Consequently, Current will no longer be carried on TWC," Hyatt wrote. "This is unfortunate, but I am confident that Al Jazeera America will earn significant additional carriage in the months and years ahead."

A Time Warner Cable spokesman said in a statement that "our agreement with Current will be terminated and we will no longer be carrying the channel."

Some media observers interpreted the move as motivated by politics.

"Time-Warner cable shows abject political and journalistic cowardice by dropping Current because of Al Jazeera deal," tweeted Dan Gilmor, a technology writer and founding director of the Knight Center for Digital Media Entrepreneurship at Arizona State University.
