In an effort to provide a more complete picture of all TV viewing, CBS now says it will periodically release audience data across all platforms for its TV shows -- including video on demand and online streaming.

The first program being offered by CBS is its nice summer hit “Under the Dome.” The season premiere of “Dome” on June 24 pulled in 13.53 million viewers when looking at Nielsen’s live-plus-same-day time-shifting data.

Adding in a full week of time-shifted viewing supplies another 4.23 million. The full seven days of time-shifting boosted adult 25-54 ratings to 6.1 from a 4.5 rating and pushed up adult 18-49 numbers to a 4.6 from 3.3.

Live plus seven days of viewing data is something that CBS and other networks regularly release. But video on demand (VOD) and online streaming data have been rarely disclosed.

CBS says the premiere of “Dome” pulled in -- for VOD -- 1,605,513 extra viewing through 22 days. Online streaming of the show through 22 days added in 484,542. All this totals 19,850,055 from all its TV-video platforms.

Data was obtained from multiple sources: Nielsen (for TV); Rentrak (VOD); and CBS Interactive Internal Data (online streaming).

It does not include Amazon Prime Instant Video figures in the streaming part of the data. Still, CBS says the first episode of “Dome” was the most-watched TV premiere in the history of the service, according to Amazon. Amazon’s Prime Instant Video provides exclusive online subscription access to all episodes of “Under the Dome” four days after the broadcast on CBS.
