Internet service providers have made progress in their bid to protect children from pornography, according to the government.
Sky has joined TalkTalk by launching family-friendly filters which customers are asked at the point of signing up if they want to use them.
BT and Virgin are set to introduce something similar within the next two months.
The filters block pornographic websites and can be switched off.
The government wants internet service providers (ISPs) to filter legal pornography and other adult subjects "by default".
Earlier this week, Sky launched Sky Broadband Shield which requires new customers to choose which filters they want, as part of the sign-up process. The 13 rating is pre-selected so customers who do not want this filter applied, need to deselect it.
Existing customers can change their preferences if they access their account on Sky's website.
