The Medford Mail Tribune made an announcement on May 19, 1910, for the new theater in town called Isis. Isis offered both vaudeville and motion pictures with music and effects. The Isis interior was luxurious by having comfortable seating, clean spaces, and an electric system of ventilation to have a nice cooling temperature inside during warm weather. Harry Williams was the manager and his goal was to provide the best entertainment experience for audiences that attend Isis. Williams partnered with Edward C. Marshall to have the Marshall Road Show perform for the Isis theater opening. The Marshall Road Show was an entertainment company with classy vaudevillians who are very outspoken in the press and recognized in various cities they have toured. This was a big deal for Medford vaudeville go-ers to check out Isis theater and get familiar with.
Isis theater opened on May 21, 1910, with The Great Marshal Road Show vaudeville performers, music performances, and the latest motion pictures. The ticket admission prices were 15 and 25 cents. Seats were not reserved and seatings were assigned on what audiences paid for.
The advertisements for the Isis theater were usually found in the Medford Mail Tribune newspapers on page four. The ad for Isis had a big and bold font inside a box with information to catch readers' attention. The information in the box provided a list of moving pictures featuring playing tor vaudevilles that will perform on stage for that night. As well as feature films or performance review articles to attract readers to Isis theater.
