Barry at Search Engine Land points to an interesting story on NAVTEQ in the St. Louis Post-Dispatch. On that same topic (mapping), I recently noticed that MapQuest had relaunched aerial imagery. They had been promising to do this for some time and it now appears back on the site. See, for example, a search for “One Market in SF, CA.” (Aerial button is in the upper right corner of the map)
MapQuest had aerial mapping years ago but abandoned it because of a lack of consumer interest. But the site has been compelled by competition to reintroduce the feature.
According to Nielsen, (November) market share breaks down as follows:
- MapQuest: 68%
- Google Maps: 28%
- Yahoo! Maps: 27%
(Numbers are greater than 100% because of multiple site usage; 42 million total users.)
