The site—BaltimoreTeacher.com—started in 2003 while Mr. Hildebrand was interning at Dunbar High School.
At the time, phones were "dumb" as far as the internet, and very few students had them anyway.
The goal of the site was to provide static links to other places on the web, and to teaching documents normally printed and distributed in class.
As technology has grown, the site has aimed to bring together dynamic content served to users based on the actual learning setting— to provide interactive content for teacher and student.
In 2012, the site was rebranded and extensively re-designed using a bootstrap framework that would optimize the viewpoints for phone, tablet or desktop.
