Nielsen Media Research and NetRatings on Wednesday officially unveiled a new database that merges information from their TV and Internet panels into a single product. The National TV/Internet Fusion
database is intended to allow media companies and advertisers analyze the relationship between TV and Internet use. That includes new data such as TV viewership by visitors to specific Web sites. The
fused database includes panelist information such as age, sex, household income and education to link the TV and Internet databases. This month, Nielsen Media will begin testing the impact of Web
measurement on TV panel-quality metrics by installing NetRatings metering technology on the computers of test homes with Nielsen People Meters.
