  • SLIDE FIVE: LINEAR TV AND BBC iPLAYER (CURRENTLY IN DRAFT, WILL BE ADDED TO PRESENTATION)
    The scale has been adjusted to compare how three individual programmes perform on BBC iPlayer compared with their linear TV rankings. We picked these three to be a selection of mainstream, breakthrough and niche programmes.
    Early indications are that programmes which skew young and niche may perform ‘disproportionately well’ on iPlayer
    EastEnders (BBC One) receives a lot of iPlayer requests, the iPlayer users only make up 2% of the whole audience
    Breakthrough: Gavin & Stacey (BBC Three) receives 240,000 requests on iPlayer, making up 7% of its total audience
    Niche: MI High attracts a relatively small BARB audience on CBBC but does extremely well, proportionately speaking, on iPlayer, with 17% of its audience

    3. 3. Copyright BBC 2008 - Confidential Clustering Users - Process 3 Data Preparation The data set consisted of sampled users who had at least 2 streaming play events. Genres and formats were represented as flags (1 – yes/0 – no). Cluster Method Various options were considered for clustering but after experimentation, a two stage approach was adopted. This involved using K- means to define a relatively large number of clusters (25-50) and then apply a hierarchical method to refine the groups. Issues • Data reduction techniques were not effective at producing standardised variables for inputs • Hierarchical clustering took a long time to process for relatively small data sets (c.3,000 users) • Main genre and formats alone were considered not to produce enough differentiation Solution 1 K-Means cluster of the main genre. Default options, 50 cluster solution. Sub genre as inputs for 4,200 users with 2+ play events. Tthe output from K-means was an input into the hierarchical technique to overcome excessive processing times. Experimented with several methods (SAS, 2008a) including average, single linkage, Wards, and maximum likelihood (ML) to produce the clearest cluster solution. A dendogram was produced for each method and ML and Wards were the most effective 7 and 6 cluster solutions respectively. Profiling suggested that clusters included programme specific groupings (Ashes-to-Ashes and Torchwood), genres (art / media / culture / documentary, soaps, comedy and children’s ) and a general group. Solution 2 Same process as solution 1 but increased the number of clusters to 11, extended the classification to include Top Gear, Science / Nature / Technology and splitting comedy between sketch and sitcoms. Solution 3 Re-ran the initial clustering as K-mediods using an option to minimise the mean absolute differences in the data and cluster medians (SAS, 2008b). This was expected to produce more robust results for binary data. The results are shown over the page.
