Twitter changes T&Cs to allow advertising

Twitter has changed its terms and conditions to allow it to implement targeted advertising across the site.

In a u-turn, Twitter founder Biz Stone, said: “In the terms we leave the door open for advertising.  We’d like to keep our options open as we’ve said before.”

The new T&Cs say the service can include ads on the site, which can be targeted according to information either submitted by the user or others.

The move comes after Stone said the microblogging site needs to generate revenue through corporate accounts.

In the past, Stone said advertising would be obtrusive to users.
