Yahoo board has reportedly decided to acquire Tumblr. The reasons for this move are many. For instance, this move could signal that Yahoo is still a relevant force in the tech sector. Also, Yahoo may be viewing this as an opportunity to appeal to a younger audience. Otherwise, this is just a move to monetize a platform that supports millions of blogs and hosts billions of posts. That is a lot of web traffic that is going to have to get used to seeing Yahoo ads.
Only time will tell if Tumblr was really worth what Yahoo paid for it. Especially since it is unknown whether members will continue to generate content and users will visit the site after any changes are implemented. If there are too many ads or if the product is allowed to become stale, such a turn of events could cause Tumblr to wither. Hopefully Yahoo has a plan in place to maintain an innovation culture at their soon to be newly acquired property.
