Since reaching a deal to buy NBC Universal in Dec. 2009, Comcast has increased its PAC contributions to election campaigns by 61% over the amount it gave in the same period leading up to the 2008 elections.

From December 2009, when the deal was reached, through August 2010, Comcast's contributions to federal candidates and political parties rose to $1.1 million from $682,450 in the same period two years earlier, Federal Election Commission records show. The money came from the company-run political action committee that funnels donations from employees....

The donations come as the FCC and other regulatory bodies go through the process of reviewing the deal amid concern that the country's largest cable company would be in control of a major broadcast network.

According to the FEC report, Comcast donated funds to 91 of the 99 House members and three of the five senators who wrote the FCC in support of the NBC sale.
