If you’ve got a beef with Comcast, you’re not alone.

On Wednesday, Sen. Elizabeth Warren took on the telecom company, which she said serves more than half of the nation’s cable and internet subscribers.

“Last year was Comcast’s best year in nearly a decade,” the Massachusetts Democrat said in prepared remarks for a speech. “But while big telecom giants have been consuming each other, consumers have been left out in the cold — facing little or no choice in service providers and paying through the nose for cable and internet service.

Warren’s speech at a forum on monopolies came as part of her advocacy for greater enforcement of antitrust laws as American consumers pay higher prices for cable and Internet services than those elsewhere.

Warren cited the cable giant specifically, along with technology players like Apple and Google, the big airlines and Wal-Mart. While the Obama administration has blocked some deals, the U.S. has been through a strong period of business consolidation.
