NEW YORK (AP) _ The Learning Channel has reversed itself and will air a half-hour show on beer in America that was put together by Anheuser-Busch, the nation's largest brewer. But it has changed the time slot.

The St. Louis-based brewer had initially obtained clearance to run its show ``An American History of Beer'' in the early afternoon of July 11-12 on the cable channel that reaches about 65 million homes.

The Learning Channel normally carries shows that deal with science, nature and history. The beer program was to appear in the weekend period typically reserved for home improvement programs.

Critics questioned the propriety of running a program on the brewing industry that was paid for by Anheuser-Busch and produced by its advertising agency.

Jonathan Rodgers, the president of Learning Channel owner Discovery Communications, abruptly pulled the show from the schedule on Tuesday.

But late Wednesday, the network said the program would run four times over the July 11-12 weekend in the 3 a.m.-9 a.m. period reserved for infomercials.

Learning Channel spokeswoman Lynn McReynolds said Thursday that airing the beer show in the regular schedule was a mistake by the programming department.

``We have a policy that this programming should air in paid programming, and we are looking into how this slipped though the cracks,'' she said.

Anheuser-Busch was pleased that its show would run on the network, company spokesman Bill Etling said.
