In October 2005, BSkyB agreed to purchase the ISP EasyNet for £211 million. At the time, EasyNet were one of two companies in the UK that had made major investments in Local-loop unbundling (LLU), providing Sky with access to 232 unbundled telephone exchanges. The purchased company was placed under a new Sky division, Sky Broadband. In October 2007, Sky reached the 1 million mark in terms of customer numbers, and claim to be adding one new customer every 40 seconds. By September 2009, it had 2.3 million customers. By July 2012 Sky had reached 4 million customers, and unbundled exchanges covering over 70% of the United Kingdom.
BSkyB agreed on 1 March 2013 to buy the fixed telephone line and broadband business of Telefónica UK, trading under the O2 and BE brands. The company agreed to pay £180 million initially, followed by a further £20 million after all customers have been transferred to Sky's existing Broadband and telephone business. and customers were transferred during 2014.
Sky Broadband provides Sky customers with download speeds of up to 20Mbit/s (ADSL2+ from Sky enabled exchanges, by means of LLU) and up to 76Mbit/s from exchanges enabled for FTTC via an Openreach landline (often still referred to as a BT line).
In July 2006, Sky also introduced a free broadband and calls package for its digital TV subscribers within the Sky Broadband network area. This means anyone on Sky can get free broadband (subject to a 2GB/month usage limit) and free evening & weekend telephone calls, as long as the line is in a Sky Broadband network area.
Sky launched Sky Broadband in the Republic of Ireland in February 2013.
As with all DSL connections, the further the distance from the DSLAM (usually located at the telephone exchange) the customer site is, the slower the line speed will be. Sky use DLM (Dynamic Line Management) over the first 10 days of a new connection to set the line at an acceptable downstream and upstream speed in order for the connection to remain stable.
Lines are initially connected at 4Mbit/s and gradually increased over the 10 day "training period" until the line shows signs of instability, this allows Sky to know what speeds the line can handle whilst remaining stable.
Sky launched fibre based broadband products in April 2012, almost 2 and half years after British Telecom launched BT Infinity in January 2010. 
Sky Wireless Hub
The Sky Wireless Hub is a wireless router distributed to all Sky Broadband customers when they order their Sky Broadband packages.
During 2006, Netgear were the only manufacturer of Sky Broadband routers, which were made in white. From 2008, Netgear and Sagem were the manufacturers of the Sky Broadband routers, made in black and shaped to match the Sky+ HD box. Both routers are also distributed in smaller boxes (The boxes are now the size of the routers) as part of BSkyB’s low carbon scheme in turn reducing postage costs. The Sagem router unlike the Netgear router has added restrictions to features such as the built in inbound firewall settings and outbound/inbound VPN connections. However a firmware upgrade is available upon request, for users wishing to connect to an outbound VPN connection using Sky Broadband, while maintaining restrictions on the inbound firewall and inbound VPN connection.
Towards the end of 2010, D-Link starting producing routers for sky. The D-Link router is the DSL-2640S.
Sky have created On Demand, which will combine Sky Broadband and Sky+ HD to offer a true on-demand service using the Ethernet socket of the Sky+ HD box and the Sky Broadband router. Sky Customers will be able to connect their Sky router to their Sky+ HD box via an Ethernet cable or Wi-Fi adapter, and stream content directly to their television. Unlike other VOD services, On Demand video will count towards a users data usage.
On 21 September 2010, the website of ACS:Law was subjected to a DDoS attack as part of Operation Payback. After the site came back online a 350mb file was uploaded containing Spreadsheets listing more than 8,000 Sky broadband customers accused of pirating adult films, this raised issues concerning Sky not following Data Protection Act guidelines.
