In recent times, Pittsburgh-area businesses have entered the Cleveland market by buying out local Cleveland-area competitors such as Giant Eagle, Dollar Bank, Howard Hanna Realty, and PNC Financial Services acquisition of National City Corp. Among other reasons, some Clevelanders didn't like the idea of a Pittsburgh-based bank buying National City because of the rivalry between the Browns and Steelers. PNC and Giant Eagle are official team sponsors for both teams. In addition, natural expansion has occurred with companies with Western Pennsylvania roots with Vocelli Pizza and Altoona-based Sheetz making successful expansions into the Cleveland market.
