Whiteboard
Albert Stallion invented whiteboards while working at Alliance in the 1960s. Alliance (now known as PolyVision) produced enameled steel for architectural cladding, but Stallion noted it could also potentially be used as a writing surface. Stallion later left Alliance to form his own whiteboard production company, MagiBoards.
Billboard (magazine)
The first issue of "Billboard" was published in Cincinnati, Ohio by William Donaldson and James Hennegan on November 1, 1894. Initially, it covered the advertising and bill posting industry, and was known as "Billboard Advertising". At the time, billboards, posters, and paper advertisements placed in public spaces were the primary means of advertising. Donaldson handled editorial and advertising, while Hennegan, who owned Hennegan Printing Co., managed magazine production. The first issues were just eight pages long. The paper had columns like "The Bill Room Gossip" and "The Indefatigable and Tireless Industry of the Bill Poster". A department for agricultural fairs was established in 1896. The title was changed to "The Billboard" in 1897.
