Tumblr set to introduce adverts
Blogging network Tumblr has said that it is set to introduce adverts on 2 May, going back on what founder David Karp said in an interview in 2010, when he claimed he was “opposed to advertising”.
Companies will be able to advertise on the dashboard section of the site, where popular blog entries are shown.
Karp has insisted that using Google ads on the site would be a "a complete last resort".
