( a ) number of subscribers corresponds to the collective sum of the total number of subscribers to each of the sbs nordic broadcast networks in sweden , norway , and denmark subject to retransmission agreements with pay television providers . ( b ) number of subscribers corresponds to dmax pay television networks in the u.k. , austria , switzerland and ireland . our international networks segment also owns and operates free-to-air television networks which reached 285 million cumulative viewers in europe and the middle east as of december 31 , 2013 . our free-to-air networks include dmax , fatafeat , quest , real time , giallo , frisbee , focus and k2 . similar to u.s . networks , the primary sources of revenue for international networks are fees charged to operators who distribute our networks , which primarily include cable and dth satellite service providers , and advertising sold on our television networks . international television markets vary in their stages of development . some markets , such as the u.k. , are more advanced digital television markets , while others remain in the analog environment with varying degrees of investment from operators to expand channel capacity or convert to digital technologies . common practice in some markets results in long-term contractual distribution relationships , while customers in other markets renew contracts annually . distribution revenue for our international networks segment is largely dependent on the number of subscribers that receive our networks or content , the rates negotiated in the agreements , and the market demand for the content that we provide . advertising revenue is dependent upon a number of factors including the development of pay and free-to-air television markets , the number of subscribers to and viewers of our channels , viewership demographics , the popularity of our programming , and our ability to sell commercial time over a group of channels . in certain markets , our advertising sales business operates with in-house sales teams , while we rely on external sales representation services in other markets . in developing television markets , we expect that advertising revenue growth will result from continued subscriber and viewership growth , our localization strategy , and the shift of advertising spending from traditional analog networks to channels in the multi-channel environment . in relatively mature markets , such as western europe , growth in advertising revenue will come from increasing viewership and pricing of advertising on our existing television networks and the launching of new services , both organic and through acquisitions . during 2013 , distribution , advertising and other revenues were 50% ( 50 % ) , 47% ( 47 % ) and 3% ( 3 % ) , respectively , of total net revenues for this segment . on january 21 , 2014 , we entered into an agreement with tf1 to acquire a controlling interest in eurosport international ( "eurosport" ) , a leading pan-european sports media platform , by increasing our ownership stake from 20% ( 20 % ) to 51% ( 51 % ) for cash of approximately 20ac253 million ( $ 343 million ) subject to working capital adjustments . due to regulatory constraints the acquisition initially excludes eurosport france , a subsidiary of eurosport . we will retain a 20% ( 20 % ) equity interest in eurosport france and a commitment to acquire another 31% ( 31 % ) ownership interest beginning 2015 , contingent upon resolution of all regulatory matters . the flagship eurosport network focuses on regionally popular sports such as tennis , skiing , cycling and motor sports and reaches 133 million homes across 54 countries in 20 languages . eurosport 2019s brands and platforms also include eurosport hd ( high definition simulcast ) , eurosport 2 , eurosport 2 hd ( high definition simulcast ) , eurosport asia-pacific , and eurosportnews . the acquisition is intended to increase the growth of eurosport and enhance our pay television offerings in europe . tf1 will have the right to put the entirety of its remaining 49% ( 49 % ) non-controlling interest to us for approximately two and a half years after completion of this acquisition . the put has a floor value equal to the fair value at the acquisition date if exercised in the 90 day period beginning on july 1 , 2015 and is subsequently priced at fair value if exercised in the 90 day period beginning on july 1 , 2016 . we expect the acquisition to close in the second quarter of 2014 subject to obtaining necessary regulatory approvals. .
