To arrest the decline of bilateral series, Richardson said a number of possibilities were discussed at the ICC annual conference in Barbados in June and would again be one of the highlights at the next Board meeting in October.
"Apart from series such as the Ashes -- which has an iconic, traditional status -- and series between India and the top Full Members, many bilateral series are perceived as having little relevance. Attendances in most series, especially for Test cricket, have fallen and the revenues generated from these series are not growing.
"Similarly the interest in and value of ICC events such as the World Cup, the Champions Trophy and World T20 has grown significantly over the last eight years or so. The increase in interest in ICC events and domestic T20 leagues effectively provides competition for the interest in bilateral international cricket series (FTP series)," Richardson told 'ESPNcricinfo' here.
"How can we grow interest in bilateral series -- bigger crowds, more people watching on television, following the series on their phones, tablets and computers? For this to happen bilateral series need greater context, a clear narrative, improved marketing and a more certain and coordinated schedule," Richardson said.
"What's the use of scheduling a series in the monsoon season or how can you expect to grow the fan base or attract attendances if series are scheduled or changed at the last minute?," he asked.
