It's been almost a decade since TiVo started rolling out trials of its digital video recorder (DVR) service. How is the DVR faring in consumers' hearts and minds? DVR adoption in the US and the UK is strong, but the rest of Europe lags, largely due to a lack of concerted efforts from local satellite and cable operators to upsell more advanced set-top boxes. Ad-skipping remains an extremely popular feature regardless of geography and is likely to remain the killer app, even as DVRs "virtualize."
