The evolution of our national telecommunications network along with advances in telephony are creating new telephone service options in the consumer marketplace. Although these new service options increase consumer choice, convenience and are often less expensive, they also engender challenges for researchers. Where the telephone researcher's traditional focus was limited to telephone versus non-telephone household biases, coverage issues now include cellular-only households and the likely undercoverage of households with non-traditional telephone landline equivalents (e.g., households subscribing to local phone service offered by cable-TV companies). International Communications Research has managed an ongoing daily telephone omnibus service (CENTRIS) for seven years. This survey focuses on and tracks many aspects of consumers' communications, entertainment, and most importantly, in-home PC/internet activity. MSG/GENESYS designed this survey and currently oversees the sampling and survey implementation. With the help of Common Knowledge, this survey vehicle is currently migrating from a strictly RDD sample to a dual frame/dual mode telephone/internet design. The primary purpose of this paper will be to communicate design issues, implementation experience and specific results, including mode variations in the standard set of tracked behaviors, attitudinal items and demographics. The paper will also review weighting and estimation issues and final procedures, specifically focusing on the overlapped portion of the sample frame (households with in-home internet access). Finally, the authors will review findings relating to samples of cellular-only and out-of-frame respondents developed through the internet portion of the sample.
