And the audience rioted

From Shakespeare The World as Stage by Bill Bryson.  Chapter 7 page 138.

In the same year that Shakespeare’s mother died, the King’s Men finally secured permission to open the Blackfriars Theatre. The Blackfriars became the template from which all subsequent indoor theaters evolved, and so ultimately was more important to posterity than the Globe. It held only about six hundred people, but it was more profitable than the Globe because the price of admission was high: sixpence for even the cheapest seat. This was good news for Shakespeare, who had a one-sixth interest in the operation. The smaller theater also permitted a greater intimacy in voice and even in music—strings and woodwinds rather than trumpet blasts.

Windows admitted some light, but candles provided most of the illumination. Spectators could, for an additional fee, sit on the stage—something not permitted at the Globe. With stage seating, audience members could show off their finery to maximum effect, and the practice was lucrative; but it contained an obvious risk of distraction. Stephen Greenblatt relates an occasion in which a nobleman who had secured a perch on the stage spied a friend entering across the way and strode through the performance to greet him. When rebuked by an actor for his thoughtlessness, the nobleman slapped the impertinent fellow and the audience rioted.
