This series commenced in January 1967 and initially ran alongside the existing WI 3000 series (see above). The "P" in WIP is variously said to stand for "Progressive" or "Pop" and reflects the fact that this new series was geared towards the new generation of rock/pop acts that Island had begun to accumulate from early 1967 onwards, as well as artists from its traditional roster who were being oriented towards the rock/pop audience, such as Jackie Edwards and Jimmy Cliff. Another change was that releases in the WIP series were normally stereo productions. Major UK top twenty singles' chart success for the label came very early in the WIP series, with WIP-6002 - Traffic's "Paper Sun" (#5, 6/1967), a classic slice of British psychedelia released just in time for the "summer of love", but quite a high proportion of the early WIP-series output was by artists who failed to develop as anticipated (e.g. Hard Meat, The Smoke) or represented one-off licensing deals with artists who never again appeared in the Island listings (e.g. WIP-6001, WIP-6013, etc.). The series continued throughout the 1970s and into the early 1980s (see below).
