The light atop the Capitol Records tower carries a message rather than blinking at random: it spells Hollywood in Morse code. Capitol president Alan Livingston proposed the idea to advertise the company’s standing as the first record label based on the West Coast. Leila Morse, granddaughter of Samuel Morse, switched it on. The message changed for a special occasion in 1992, when the light blinked Capitol 50 to mark the record company’s fiftieth anniversary. The tower stands at 1750 Vine Street.
