The lobbying industry had a record year in 2021, taking in $3.7 billion in revenue as companies, associations and other organizations pressed Congress and the Biden administration over trillions of dollars in new pandemic spending and rules affecting health care, travel, tourism and other industries. The revenue figures, compiled in recent weeks from government records by OpenSecrets, show that lobbying spending began steadily growing in 2017. The jump in 2021, when lobbying spending was about 6 percent higher than 2020, came as the government's pandemic interventions and record expenditure took center stage. The surge came as companies and associations aimed to roll back regulations on their industries " many of them pandemic-related " while others vied for a slice of the trillions in new spending. Manufacturers, unions, financial companies and technology firms all spent significantly more in 2021 than in previous years. Thousands of companies and organizations appeared to hire lobbyists for the first time during the pandemic, as more than 3,700 companies and other groups that spent no money lobbying the government in 2019 paid lobbyists last year. The pharmaceutical industry, regularly one of the biggest spenders in Washington, also increased its spending. Its top trade group, the Pharmaceutical Research & Manufacturers of America (PhRMA), topped $30 million in spending last year, up 17 percent from the year prior.
