Title:
The_Times

Context:
The Times faced financial extinction in 1890 under Arthur Fraser Walter, but it was rescued by an energetic editor, Charles Frederic Moberly Bell. During his tenure (1890–1911), The Times became associated with selling the Encyclopædia Britannica using aggressive American marketing methods introduced by Horace Everett Hooper and his advertising executive, Henry Haxton. Due to legal fights between the Britannica's two owners, Hooper and Walter Montgomery Jackson, The Times severed its connection in 1908 and was bought by pioneering newspaper magnate, Alfred Harmsworth, later Lord Northcliffe.

Which encyclopedia was The Times aggressively selling to American markets?
