Specific data on Luxembourg is difficult to come by but based on the aggregate data for the European region and extrapolated results there are:
households (82.1%) with internet access at home
households (81.9%) with a computer
households (29.6%) with a fixed broadband subscription
households (78.2%) with an active mobile broadband subscription
(120.6%) mobile cellular telephone subscriptions
(37.3%) fixed telephone subscriptions
Luxembourg is one of the countries which has higher total internet advertising growth and higher mobile internet penetration.
These countries usually have strong economies with established Internet advertising sectors. Extensive telecoms infrastructure prompted early consumer adoption of both fixed broadband and mobile internet access. Most fixed broadband markets are not yet saturated, leaving room for further wired internet advertising revenue growth as connectivity increases.
