DESCRIPTION:Using nine months of access logs comprising 1.9 Billion sessio
 ns to BBC iPlayer\, we survey the UK ISP ecosystem\nto understand the fact
 ors affecting adoption and usage of a high bandwidth TV streaming applicat
 ion across different providers.\nWe find evidence that connection speeds a
 re important and that external events can have a huge impact for live TV u
 sage. Then\,\nthrough a temporal analysis of the access logs\, we demonstr
 ate that data usage caps imposed by mobile ISPs significantly affect\nusag
 e patterns\, and look for solutions. We show that product bundle discounts
  with a related fixed-line ISP\, a strategy already\nemployed by some mobi
 le providers\, can better support user needs and capture a bigger share of
  accesses. We observe that\nusers regularly split their sessions between m
 obile and fixed-line connections\, suggesting a straightforward strategy f
 or offloading\nby speculatively pre-fetching content from a fixed-line ISP
  before access on mobile devices.\n
