Time Warner Cable (TWC) is experimenting with cheaper bundles to keep people from cancelling cable: The pay TV provider just introduced a Starter TV with HBO bundle that includes access to 20 channels, including local broadcasters in HD, as well as HBO and HBO Go, for $30 a month (hat tip to Lightreading). TWC is the second cable company to experiment with this kind of cheap bundle after Comcast started offering a similar bundle in October. As with the Comcast bundle, it’s worth noting that the actual price on a consumer’s monthly bill won’t be $30. In order to actually watch any of these local channels, consumers still need to rent a cable box, which currently costs $10 a month. Add various fees and taxes, and you’ll more likely end up with a monthly bill of around $45 to $50 — and that doesn’t even include internet access or a DVR.
