Comcast is introducing a new $1.99/month fee for equipment that allows customers with older televisions to watch the cable television lineup they already pay to receive.

Customers with Digital Transport Adapters, also known as DTAs, will soon find the new fee on their Comcast bill. Comcast formerly offered up to two DTA boxes for free in areas where the company reclaimed space on cable systems by moving analog television channels to digital. Customers needing more than two boxes paid $1.99 for each additional box, but now Comcast will charge everyone for the devices.

Comcast expects to earn more than $550 million in new revenue nationwide from the introduction of the new fee.

Customers are unhappy.

“So after paying more than $60 a month for a television package, we now have to shell out even more for the equipment to watch it,” asks Stop the Cap! reader Deepak in Philadelphia, one of the first cities where Comcast will levy the fee. “Comcast says we cannot buy our own box or buys theirs outright to avoid paying the fee either.”

The devices cost Comcast an estimated $35-50 each, depending on their capabilities, so Comcast will book the additional revenue as profit as early as mid-2014.
