"In addition to using Google Maps to get local business details, read reviews, and check out photos, I can now also get a sneak peek with embedded videos. Local business owners can easily add YouTube videos along with other content such as business details, photos, and descriptions to their listings. To do so, simply upload your videos to YouTube and ensure that the 'embed' option is turned on," explains Google LatLong Blog.
Online video is more than YouTube and Google Video, but Google seems to ignore this. Even if YouTube's US market share is 73.18% (according to Hitwise), it's unreasonable to think that YouTube should aggregate all the videos that are available online. Google should encourage diversity and choices, instead of selecting the most convenient options.
