The PGA Championship (often referred to as the US PGA Championship or USPGA outside the United States) is an annual golf tournament conducted by the Professional Golfers' Association of America. It is one of the four men's major championships in professional golf.

It was formerly played in mid-August on the third weekend before Labor Day weekend, serving as the fourth and final men's major of the golf season. Beginning in 2019, the tournament is played in May on the weekend before Memorial Day, as the season's second major following the Masters Tournament in April. It is an official money event on the PGA Tour, European Tour, and Japan Golf Tour, with a purse of $11 million for the 100th edition in 2018.

In line with the other majors, winning the PGA gains privileges that improve career security. PGA champions are automatically invited to play in the other three majors (Masters Tournament, U.S. Open, and The Open Championship) and The Players Championship for the next five years, and are eligible for the PGA Championship for life. They receive membership on the PGA Tour for the following five seasons and on the European Tour for the following seven seasons. The PGA Championship is the only one of the four majors that is exclusively for professional players.

The PGA Championship has been held at various venues. Some of the early sites are now quite obscure, but in recent years, the event has generally been played at a small group of celebrated courses.

user: Given a refrence text about The Bobcaygeon Independent, tell me when it was established and when it ceased publication.

assistant: <think>
The Bobcaygeon Independent was the weekly community newspaper in Bobcaygeon, Ontario, Canada. It was established in 1869. Ownership changed hands many times over the years, until it was purchased along with then owner, Citizens Communication Group, in 2000 by Metroland Publishing.

The Independent covered everything from community events, school issues & family milestones to local crimes and tragedies. During ownership by the Citizens Communication Group, the Bobcaygeon and Fenelon news teams worked closely together, and from time to time, some stories of general interest would run simultaneously in the Independent and its sister paper the Fenelon Falls Gazette. During ownership by Metroland Publishing, a similar news style was used with common pages in both Bobcaygeon and Fenelon papers, and in the Lindsay This Week newspaper.

The paper was officially incorporated into Kawartha Lakes This Week in late 2004 in keeping with the amalgamation of Lindsay, Bobcaygeon and Fenelon Falls into the City of Kawartha Lakes.

Today, back issues are available at the Bobcaygeon Public Library for viewing on Microfiche, as far back as the first issue in 1869.

Although the paper had ceased publication in 2004, the website Amazon.com still offers subscriptions.</think>

Obviously everyone has their own preferences and styles they prefer, but more often than not, these are the 5 rappers mentioned in most lists. These rappers all had great commercial success and critical acclaim from the industry and their peers.
