Per the TWC release:

The Internet transformation will begin this summer and will include speed increases on TWC residential Internet plans at no additional cost, with customers experiencing increases up to six times faster, depending on their current level of Internet service. For example, customers who subscribe to Standard, formerly up to 15 Mbps, will now receive up to 50 Mbps, customers who subscribe to Extreme, formerly up to 30 Mbps, will now receive up to 200 Mbps; and customers who subscribe to Ultimate, formerly up to 50 Mbps, will receive up to 300 Mbps, at no extra charge.

What's more, the company plans to offer its Ultimate service for just $65, five bucks cheaper than Google's Fiber service. However, TWC did not disclose how fast that Ultimate broadband would be. More importantly, this isn't the first time that we've seen Google send the reigning ISPs scrambling. Comcast Atlanta suddenly began offering a new fiber service reportedly twice as fast as Google's and AT&T dropped its existing fiber package prices in both Austin and Kansas City to match. It doesn't matter if you subscribe to the Google service or not; the mere fact that there's now competition in this market is enough to bring down prices for everybody.
