NEW YORK, December 4, 2000 - Although holiday online advertising activity this season is nearly four times what it was last year, online advertisers are off to a slower start, according to a report released today by AdRelevance, a Jupiter Media Metrix company (NASDAQ: JMXI) and innovator in next-generation Internet advertising measurement technology. The AdRelevance Report reveals that while the number of retailers advertising online this season (2313) almost quadrupled from 1999 (657), ad impressions are growing slower, total median impressions per retailer are down and the number of holiday-themed ads in October 2000 is less than half of what it was last year.

Key findings from the latest AdRelevance Holiday 2000 Intelligence Report, which tracks and analyzes all holiday-related online advertising from October 2000 through mid-November 2000, include:

• Online holiday ad impressions and spending by retailers did not post gains above last year until the second week of November 2000.
• Due to the significant increase in total retail advertisers, total median online ad impressions per retailer were down 82 percent in October 2000 - falling from 130,000 impressions in 1999 to 23,000 this season.
• Only five of last year's top 10 holiday advertisers show up in this season's rankings: Ubid, Yahoo!, eBay, barnesandnoble.com and Amazon.com.
• Although their rankings are reversed, "books, music & movies" (#1 this year) and "auctions" (#2 this year) are still the top two most promoted retail products on the web. Unseating "toys" and "office equipment and supplies" in this year's top 10 advertised retail products are "gifts & party supplies" and "flowers."

"Despite high levels of holiday-related online advertising this season, it is becoming clear that retail advertisers are starting a little later this year. The truth of the matter is that seasonal online advertising impressions and expenditures grew faster in 1999 than 2000, through about mid-November," said Charles Buchwalter, vice president of media research for AdRelevance. "It's interesting to note too that during the first six weeks of the fourth quarter, only 14 companies - out of roughly 2700 retail online advertisers - made up 50 percent of all retail online ad impressions."

Who's Leading the Charge?
Although Amazon.com once again leads the holiday online advertising charge in 2000, strong competition is riding on its heels (see Table B above):

• Barnesandnoble.com, which ranked six last year among top holiday online retail advertisers, increased its share of the online ad pie by nine percent - becoming the second largest online holiday advertiser.
• Announcing they would start online advertising early this season to encourage early shoppers, BestBuy.com posted one of the strongest online ad gains, becoming the number eight advertiser this year. Last year, BestBuy.com did not run an online campaign until late December.

"While the latest AdRelevance data does not define the final outlook for the 2000 holiday season, it does suggest that by starting slow, retailers do not seem to have learned much from last year's holiday online advertising lessons," Buchwalter said.
