over 15 million fans attended our amphitheater shows throughout the year which is a record for live nation where kid rock , luke bryan and 5 seconds of summer played to sold out audiences over the summer . our efforts to enhance our amphitheater onsite business got off to a great start in 2015 with our new food and beverage and point of sale partners offering more selections and a faster transaction process . in our international business , we saw growth in our new asian markets - thailand , taiwan and indonesia - while large tours by the popular korean act bigbang as well as fleetwood mac in australia grew ticket revenue in our pan-asian business . this growth more than offset a decline in stadium activity in both north america and europe which is a function of the mix of artists touring in the year . our operating income for the year improved over 2014 largely due to the impact of the goodwill impairment in 2014 which was partially offset by higher depreciation and amortization in 2015. we will continue to look for expansion opportunities , both domestically and internationally , as well as ways to market our events more effectively , in order to continue to expand our fan base and geographic reach and to sell more tickets and onsite products . our ticketing segment revenue for the year increased by $ 82.3 million on a reported basis as compared to last year , or $ 156.3 million , a 10 % increase , without the impact of changes in foreign exchange rates . this increase was largely due to a 4 % growth in primary ticket sales globally , driven by increased sales for concert and sporting events . as we continued to improve our platform and provide consumers with a broader range of secure ticketing options , visits to our websites increased by 10 % in 2015 with nearly 60 % of these visits occurring on mobile devices . our resale business also grew during the year in north america , europe and australia , with gross transaction value , or gtv , improving by 32 % on a reported basis year-over-year . mobile continues to be an area of focus and innovation for us and in 2015 , 21 % of our total tickets were sold via mobile and tablet devices and our total mobile ticket sales increased by 20 % year-over-year . operating results for the year increased over 2015 , largely as a result of strong primary ticket sales as well as our growing resale ticketing business . we will continue to implement new features to drive further expansion of mobile ticket transactions and invest in initiatives aimed at improving the ticket search , purchase and transfer process . as a result , we expect to attract more ticket buyers and enhance the overall fan and venue client experience . our artist nation segment revenue for the year increased by $ 44.8 million on a reported basis as compared to last year , or $ 51.4 million , a 13 % increase , without the impact of changes in foreign exchange rates driven by higher management commissions and sports-related revenue . artist nation 's operating results were flat to 2014 as the impact of the goodwill impairment in 2014 was largely offset by higher investment in new business lines in 2015 as well as higher amortization associated with recent acquisitions . our artist nation segment is focused on managing its existing clients as well as developing new relationships with top artists and extending the various services it provides . our sponsorship & advertising segment revenue for the year was up $ 33.4 million on a reported basis as compared to last year , or $ 51.6 million , a 17 % increase , without the impact of changes in foreign exchange rates . higher revenue resulted from new clients , increased festival sponsorships , and expansion of our business in australia and asia , all of which also increased our operating income . our growth has been driven by the expansion of our festival footprint and engaging new sponsor clients with both our existing events and new brands added to our festival family . operating income for the year improved by 5 % on a reported basis which was driven by higher revenue , partially offset by the impact of changes in foreign exchange rates . we believe that our extensive on-site and online reach , global venue distribution network , artist relationships , ticketing operations and live entertainment content are the key to securing long-term sponsorship agreements with major brands , and we plan to expand these assets while extending further into new markets internationally . 27 we continue to be optimistic about the long-term potential of our company and are focused on the key elements of our business model : expand our concert platform , sell more tickets and invest in product improvements , grow resale ticket volume , grow sponsorship and advertising and drive artist management through our other core businesses . segment overview our reportable segments are concerts , ticketing , artist nation and sponsorship & advertising . concerts our concerts segment principally involves the global promotion of live music events in our owned or operated venues and in rented third-party venues , the operation and management of music venues , the production of music festivals across the world and the creation of associated content . while our concerts segment operates year-round , we experience higher revenue during the second and third quarters due to the seasonal nature of shows at our outdoor amphitheaters and festivals , which primarily occur from may through october . revenue and related costs for events are generally deferred and recognized when the event occurs . all advertising costs incurred during the year for shows in future years are expensed at the end of the year .

the impact of changes in foreign exchange rates , depreciation and amortization increased $ 36.7 million , or 32 % , primarily due to higher amortization associated with certain revenue generating

improvements and incremental depreciation and amortization of $ 18.5 million from the acquisitions discussed above . concerts recorded a goodwill impairment of $ 117.0 million related to our international concerts business in the fourth quarter of 2014 in connection with our annual impairment test . there was no impairment charge recorded during 2015. concerts acquisition transaction expenses increased $ 6.6 million during the year ended december 31 , 2015 as compared to the prior year primarily due to an increase in the fair value of a put option held by a third party to sell its noncontrolling interest in one of our subsidiaries to us . the decreased operating loss for concerts for the year ended december 31 , 2015 was primarily driven by the 2014 goodwill impairment and higher bad debt reserves . 34 year ended 2014 compared to year ended 2013 concerts revenue increased $ 209.7 million , or 5 % , during the year ended december 31 , 2014 as compared to the prior year .

noted above . concerts selling , general and administrative expenses increased $ 33.9 million , or 5 % , during the year ended december 31 , 2014 as compared to the prior year primarily due to higher

the year ended december 31 , 2014 as compared to the prior year primarily due to higher impairment charges and amortization acceleration of certain intangible assets recorded during 2013. we recorded impairment charges of $ 8.6 million in 2013 primarily associated with venue management and leasehold intangible assets when it was determined that the estimated undiscounted cash flows associated with the respective intangible asset was less than its carrying value . in addition , in 2013 we accelerated $ 6.7 million of amortization associated with a change in the estimated useful lives of certain
