Hotels.com put more of its online ad duties with Avenue A/Razorfish, according to AdWeek. Only in May, Razorfish took over much of the media planning and buying for web display ads and will now add search engine marketing, a duty that U.K.-based Greenlight had hoped to keep by opening up a New York office in February.

The IAC-owned Hotels.com has been a peregrinatious account, shifting various parts of the work to various agencies over the past half decade. Doner took over the creative portion of the account a little more than a year ago from Hill Holliday.

Much speculation has attended the fate of Hotels.com's spending in the face of IAC's planned consolidation of its web properties into two holding companies, one a travel-related venture with Hotels.com as an anchor property. Financially, IAC's recent poor performance has been blamed specifically on its two main travel sites, Hotels.com and Expedia.
