Sky announced on Friday it would give Sky Sports customers one free year of Sky Broadband Unlimited (£14.50 line rental) or six months free of Sky Fibre Unlimited (£20 per month after and £14.50 line rental) - as long as they make the switch from BT.
Following an announcement that BT Sport would give broadband customers free access to live sports, both new and existing Sky Sports subscribers will now have access to the unlimited internet connections, according to the Guardian.
The deal will not impose monthly download restrictions or fees for extra data use. In addition, Sky subscribers without a sports package will have the opportunity to upgrade to Sky Sports for half the normal price of £7.50.
BT Sport first revealed in May that all BT broadband customers would have free access to its suite of channels. The service costs £3 a month for HD content, but BT Sport said it would waive the fee for a year if customers signed up before 1 August.
The decision left competitor Sky claiming its services were cheaper and better, and soon both companies were dueling for the chance to offer sports customers a premium broadband service at little or no expense. BT already responded to Sky's news on Friday and claimed the company is still "overcharging fans".
Sky's pricing for service pans out higher than BT's, according to the Telegraph, but the company still offers more sports TV coverage. Sky provides 116 exclusive live Premier League games per season, for instance, whereas BT offers 38 games.
