One of Europe’s largest publishers, Axel Springer, has stepped up its efforts to protect online advertising revenues by banning readers who use ad blockers from accessing its Bild tabloid website. Bild, Europe’s top-selling tabloid, will now ask visitors to turn off their ad blocker or pay a monthly subscription fee of €2.99 which then allows browsing with limited ads. In a statement released today Bild.de said “whoever does not switch off the ad blocker or does not pay cannot see any content on Bild.de, as of now”.
