With the election of Barack Obama, it was only a matter of time before the battle for net neutrality reared its head again. Now, a high-ranking senator plans to introduce a bill in January that will prevent ISPs from blocking web content.

Net neutrality -- the crusade against allowing ISPs to charge different rates for more bandwidth-intensive content -- became a major issue this summer when it became public that Comcast was slowing and sometimes blocking certain file transfers. The Federal Communications Commission ultimately stepped in and ordered Comcast to stop inhibiting the transfer of files,  but Sen. Byron Dorgan of North Dakota feels a law is necessary to prevent service providers from discriminating against internet content, according to a Reuters report.

President-Elect Obama supports net neutrality, as do several content companies including Google, Microsoft and eBay. Comcast, meanwhile, is suing the FCC for its decision while other ISPs are complaining Dorgan's proposed law is unnecessary.

"The current principles already deal with unreasonable discrimination," said AT&T executive VP Jim Cicconi, who added that blocking content wouldn't be a wise business move for AT&T. "We'd be shooting ourselves in the foot."
