 We have started providing an audience management feature to utilize
 client data and audience data of Yahoo! JAPAN without operational
 By using this feature, the management of the audience list (former
 target list) and the management of the audience source (data source)
 are separated, which makes it easier to manage the data.
 We plan to expand the client data source and gradually provide
 features that make it easier to utilize the audience data of Yahoo!
 JAPAN in the future.

4. Changes:
 The following features were added or changed as the first audience
 management feature.

  list," and "audience list targeting" will be newly established as a
  general term for targeting using the audience list.

  management feature.

  to be available after the name change to the Audience list.
  -After the released date, you can no longer upload linked data files
  when creating a new "custom" audience list.
  Additional file uploads are available by editing the list already

  that has the same feature.
