Today Yahoo! announced that it is acquiring Tumblr . This marks a revival of Yahoo’s efforts to get into the social space. This inspired me to look back on the history of Yahoo’s social efforts. The following is listed in chronological order by when Yahoo! acquired/launched the property:
Flickr (March 2005 to Present)
Yahoo! acquired Flickr to get into the photo sharing business, and Flickr later replaced Yahoo! Photos as it did not make sense to have two Photos properties for Yahoo!. Flickr is still going strong today, ranked as the 82nd most popular website in the world according to Alexa.
