Hi Jason,

This is a licensing agreement through our marketing department. It’s
just another component of a licensing program that we’ve had in place
for several years for a variety of items such as computer peripherals
and we’re now extending to additional items such as those you see in the
photograph.

The manufacturer is Diamond Electronics and we will be providing our
branding and logo. The manufacturer is working to sell these products
into major retailers.

It’s an exciting extension of the Yahoo! brand, but it won’t be a
significant announcement for the company as the blog suggests.

Thanks,
