JUPITERMEDIA CORPORATION REPORTS RESULTS FOR ITS THIRD QUARTER ENDED SEPTEMBER 30, 2003

Meckler. "Our June 30, 2003 acquisition of the ArtToday.com Network and its graphics-oriented readership expands and diversifies our Online Media revenues. The ArtToday.com Network is one of the leading paid subscription resources on the Web. In addition, the acquisition of DevX.com and its leading developer-oriented readership, which we announced in July, expands our resources for the Web development community.
