* Early 1900s: Horoscopes were already appearing in some publications, mainly women's magazines and Sunday supplements. These were often presented as "astrological forecasts" or "star readings".
* 1930s: Horoscopes became more popular, particularly during the Great Depression when people sought solace and hope in predictions.
* Post World War II: Daily newspapers started featuring horoscopes more regularly, aiming to attract a wider readership. The format shifted to the more familiar "sun sign" readings we know today.
Notably:
* 1930s: The influential "Your Stars Today" column by R.H. Naylor appeared in the New York Daily News, which contributed significantly to the widespread acceptance of daily horoscopes.
* 1940s: The New York Post and Chicago Tribune also introduced daily horoscopes, further solidifying their inclusion in newspapers.
So, while there's no definitive date, the 1930s and 1940s are considered key periods for the rise of horoscopes in daily newspapers.
Remember, this is a simplified timeline. Researching specific newspapers and astrologers from that era would provide more detailed information about their individual journeys.
