What year did televisions appear in the US?

Although many people claim television was invented by Philo Farnsworth in America, it was actually invented by John Logie Baird, a Scotsman who carried out his research in London England. He first demonstrated his system in 1925 and it was in commercial use by 1929.

Philo Farnsworth is credited with the first fully electronic television with no moving parts but this was not until 1929.
