Can anyone tell me why some business names on google maps are in bold and others are not? It you search for "IT recruitment" and look at the results in Christchurch New Zealand you will see that some businesses are listed in bold on the map and others are not.

We want 'sourced' which is an IT Recruitment business to be in bold and cannot figure out how to make this occur and cannot find any docs on this.

Any help would be appreciated.
