At this point, Gallup was compiling a Top 200 singles chart and slots game Top a hundred and free slots online fifty albums chart for industry insiders, with the information accessed by subscribing to Music Week's spin-off publication Charts Plus. Subsequently, CIN sought to develop new advertising and marketing opportunities and sponsorship offers; these included premium-fee fax and telephone companies and the chart newsletters Charts Plus (published from May 1991 to November 1994) and Hit Music (printed from September 1992 to May 2001).

Beginning in May 1991 Charts Plus featured singles charts Free Slots with bonus and Free Spins no download positions 76-200 (plus artist albums positions 76-150, Top 50 compilations, and several style and format charts). In September 1992, a second e-newsletter was created: slots free Hit Music, a sister publication of Music Week featuring (among other charts) the singles Top seventy five and a revived "Next 25". In November 1994, Slots Charts Plus ceased publication; Hit Music expanded its chart coverage to an uncompressed (without special rules) Top 200 Singles, slots game Top 150 Artists Albums and slots game Top 50 Compilations.

On the chart of 16 August 2014, Nico & Vinz's "Am I Wrong" jumped from quantity fifty two to no 1 in its sixth week, after the streaming hit (the first single ever to chart in the top 75 on streams alone) grew to become accessible to buy. Kate Bush had the largest document within the UK final week, but she's not No.1 on the Official Chart. Some unbiased retailers misplaced access to the record-label-funded Electronic Record Ordering System (Eros); it was "too costly to make it Year 2000 compliant".

Gallup attempted to block Millward Brown's new chart by complaining to the Office of Fair Trading in regards to the contractual clause by which BARD retailers exclusively supplied gross sales information to CIN, but the interim order was rejected. In February 1997, CIN and BARD agreed to a brand new 18-month deal for the charts. In June 1995 the case was dropped, after the clause permitting BARD retailers to supply sales data to other chart compilers was deleted; as a result of CIN retained the copyright, different compilers could not use (or sell) the information.

It was introduced in June 2014 that as of Sunday, 29 June, audio streams from providers such as Spotify, Deezer, Napster, O2 Tracks, Xbox Music, Sony Unlimited, and rara would depend for the Official Singles Chart, to reflect changing music consumption in the United Kingdom.
