Advertisers of the yearWhile tunnelbuilder is free to web and readership driven, somebody has to pay the tab. Our advertisers, who are readers themselves, are the people to thank. Amongst these, foundation sponsors Herrenknecht, Robbins, NFM Technologies and Aker Wirth are now into their 13th year of continuous advertising. A glance at tunnelbuilder adtracker shows readers are awarding them top clickthroughs, with Herrenknecht once again our advertiser of the year. Main sponsors Normet, DSI, CBE, Robit, Terratec and BASF Meyco are also doing nicely, as are our faithful band of core advertisers. It seems that the combination of accurate journalism, qualified readership and world-beating products is working well! 27/11.
